Which of the following wavelengths of light has the greatest amount of energy?
Red waves have a relatively long wavelength (in the 700 nm range), and violet waves are much shorter ” roughly half that. Because violet waves have the shortest wavelength of the visible light spectrum, they carry the most energy.
What is the Sun’s energy output quizlet?
How much energy does the Sun emit per second? The Sun emits 3.8 x 10^33 ergs/sec or 3.8 x 10^26 watts of power, an amount of energy each second equal to 3.8 x 10^26 joules. In one hour, or 3600 seconds, it produces 1.4 x 10^31 Joules of energy or 3.8 x 10^23 kilowatt-hours.
How much energy does the Sun emit per second?
Researchers use a measurement of luminosity to define the amount of energy the sun can emit. Luminosity is recorded in Joules per second internationally. The sun’s luminosity is about 3.8 x 1026 Joules a second. In terms of mass, you can think of the total energy output as about 4,000,000 tons every second.
Does the sun emit long or short wavelength energy?
The sun emits shortwave radiation because it is extremely hot and has a lot of energy to give off. Once in the Earth’s atmosphere, clouds and the surface absorb the solar energy. The ground heats up and re-emits energy as longwave radiation in the form of infrared rays.
What is the wavelength of heat energy?
Thermal radiation is electromagnetic radiation emitted from all matter that is at a non-zero temperature in the wavelength range from 0.1 μm to 100 μm. It includes part of the ultraviolet (UV), and all of the visible and infrared (IR).
What frequency does the sun emit?
The sunlight that we see ” aptly named visible light ” falls into only a very narrow range of the spectrum, from about 400 to 750 nanometers (a nanometer is one-billionth of a meter, or about 400 millionths of an inch). The Sun also emits at longer wavelengths, in the infrared, microwave, and radio.
How does the sun emit different wavelengths?
Not only does the sun contain many different atoms ” helium, hydrogen, iron, for example ” but also different kinds of each atom with different electrical charges, known as ions. Each ion can emit light at specific wavelengths when it reaches a particular temperature.
Why does the sun emit most of its energy in visible light?
Radiation from the Sun The sun gets its energy from the process of nuclear fusion. This process occurs in the sun’s core or interior, where temperature and pressure are extremely high. During most of the sun’s life, energy comes from the fusion of hydrogen nuclei.
Does the sun emit all electromagnetic waves?
The Sun emits radiation right across the electromagnetic spectrum, from extremely high-energy X-rays to ultra-long-wavelength radio waves, and everything in-between. The peak of this emission occurs in the visible portion of the spectrum.
Which wave carries least energy?
Radio waves have photons with the lowest energies. Microwaves have a little more energy than radio waves. Infrared has still more, followed by visible, ultraviolet, X-rays and gamma rays.

Among all the visible rays, violet ray has the highest frequency, Thus violet ray has the highest energy.
Why does the Sun appear to have a sharp edge?
Despite being a huge ball of gas, the Sun appears to have a sharp edge because the energy radiates from a thin layer only a couple hundred miles thick, compared with the Sun’s overall radius of 432,000 miles (695,000 kilometers).
Why do we think the pressure and temperature inside the Sun is so high?
Because nuclear reaction have decreased the weight of the core of the sun, increasing the pressure. The core of the sun contracts under its own pressure, and this pressure travel outwards, increasing the temperature of the sun. And as temperature increases, luminosity and the fusion rate increase.
What is Helioseismology and what does it tell us about the Sun?
Helioseismology is the study of solar surface patterns, and it can tell us information about the surface of the Sun, as well as give us clues to the composition of the interior as well.
How much energy does the sun emit each day?
At any moment, the sun emits about 3.86 x 1026 watts of energy. So add 24 zeros to the end of that number, and you’ll get an idea of how unimaginably large an amount of energy that is! Most of that energy goes off into space, but about 1.74 x 1017 watts strikes the earth.
How much solar energy does the sun produce a day?
Since a 60-watt bulb consumes 60 watt x hours in one hour, or 60 Wh x 24 hr/day = 1440 Wh per day and there are 120 trillion square meters in our atmosphere, that’s like dropping 120 TRILLION 60 watt light bulbs and still having enough electricity in one hour of sunlight for ALL of those light bulbs to shine for 24 …
How much energy does the sun emit in a year?
The sun produces 1.23 x 10 ^ 35 Joules of energy in one year. To compare, a nuclear weapon only gives off 4.18 x 10 ^ 15 Joules of energy, which is less energy than the Sun produces in ONE SECOND. All this heat energy is what powers life here on Earth, and is strong enough to be felt 150 million kilometers away.
At what wavelength does the sun emit the most radiation in microns?
For the Sun, the wavelength at which the maximum energy is emitted is 520 nanometers, which is near the middle of that portion of the electromagnetic spectrum called visible light.
How does the sun produce energy?
Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun’s core and fuse to create a helium atom. This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of energy.
Where does the energy that the sun emits come from?
The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun’s core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released.
Does sunlight produce heat?
The Sun produces light by a nuclear reaction called fusion. As atoms of hydrogen combine to form helium, they produce vast amounts of heat and light. … The central core of the sun, where heat and light are produced, has a temperature of 15 million degrees.
How does the heat from the sun reach the Earth?
Radiation is the transfer of heat energy through space by electromagnetic radiation. Most of the electromagnetic radiation that comes to the earth from the sun is invisible. Only a small portion comes as visible light. Light is made of waves of different frequencies.
How does energy from the sun heat up an object?
Tom Zepf of the physics department at Creighton University in Omaha, Neb., notes that “Sunlight heats a material such as water or a brick primarily because the long wavelength, or infrared, portion of the sun’s radiation resonates well with molecules in the material, thereby setting them into motion.
What is the relationship between wavelength and frequency?
Frequency and wavelength are inversely proportional to each other. The wave with the greatest frequency has the shortest wavelength. Twice the frequency means one-half the wavelength.
Which wavelengths does earth radiate to space?
Outgoing Long-wave Radiation (OLR) is electromagnetic radiation of wavelengths from 3″100 μm emitted from Earth and its atmosphere out to space in the form of thermal radiation. It is also referred to as up-welling long-wave radiation and terrestrial long-wave flux, among others.

Wavelength range and sources Infrared radiation (IR), also known as thermal radiation, is that band in the electromagnetic radiation spectrum with wavelengths above red visible light between 780 nm and 1 mm. IR is categorized as IR-A (780 nm-1.4 µm), IR-B (1.4-3 µm) and IR-C, also known as far-IR (3 µm-1 mm).
Why does the sun emit energy mostly in the form of light while Earth radiates at longer wave lengths?
In total approximately 70% of incoming radiation is absorbed by the atmosphere and the Earth’s surface while around 30% is reflected back to space and does not heat the surface. The Earth radiates energy at wavelengths much longer than the Sun because it is colder.
What is most of the energy that reaches Earth from the sun?
The energy from the sun that reaches Earth’s surface is mostly “shortwave” radiation ” mostly visible light. This energy passes freely through the atmosphere and is absorbed by Earth’s surface. The surface warms from the energy input, and some of its heat projects back to the atmosphere as infrared radiation.
Which of the following absorb the energy from the sun?
About 23 percent of incoming solar energy is absorbed in the atmosphere by water vapor, dust, and ozone, and 48 percent passes through the atmosphere and is absorbed by the surface. Thus, about 71 percent of the total incoming solar energy is absorbed by the Earth system.

Does wavelength affect energy?
The amount of energy is directly proportional to the photon’s electromagnetic frequency and thus, equivalently, is inversely proportional to the wavelength. The higher the photon’s frequency, the higher its energy. Equivalently, the longer the photon’s wavelength, the lower its energy.
What is the relationship between wavelength and energy?
Just as wavelength and frequency are related to light, they are also related to energy. The shorter the wavelengths and higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy. The energy equation is E = hν.
How does frequency and wavelength affect the energy carried by the wave?
Explanation: Long wavelength, low frequency waves, such as radio wave seas are thought to be harmless. They don’t carry much energy and are therefore considered safe by most people. As the wavelength decreases and frequency increases, the energy increases ” for example X-rays and gamma radiation.
