The answer is “a hammer hitting a metal cup”. Sound waves are formed when a vibrating object makes the encompassing medium vibrate. A medium is a material in which a wave goes through.
What object produces sound waves?
Sound is produced when an object vibrates, creating a pressure wave. This pressure wave causes particles in the surrounding medium (air, water, or solid) to have vibrational motion. As the particles vibrate, they move nearby particles, transmitting the sound further through the medium.
What causes sound waves quizlet?
Sound waves are produced by vibrations that push and pull on the medium that surrounds them and then sends out waves. The particles come together and then spread apart repeating this cycle. You just studied 21 terms!
What causes sound in an object?
Sound is a type of energy made by vibrations. When an object vibrates, it causes movement in surrounding air molecules. These molecules bump into the molecules close to them, causing them to vibrate as well. This makes them bump into more nearby air molecules.
What affects the sound of a wave?
During propagation, waves can be reflected, refracted, or attenuated by the medium. The behavior of sound propagation is generally affected by three things: A complex relationship between the density and pressure of the medium. This relationship, affected by temperature, determines the speed of sound within the medium.
What are the five sources of sound?
Acoustic instruments, Electrical instruments, Living beings like animals and birds using their vocal cords, Man-made sources like machines, any vibration caused by wind are five sources of sound.
What are the 4 properties of sound?
Since sound is a wave, it has all of the properties attributed to any wave, and these attributes are the four elements that define any and all sounds. They are the frequency, amplitude, wave form and duration, or in musical terms, pitch, dynamic, timbre (tone color), and duration.
How do sound waves travel quizlet?
As sound travels through the air, it creates a disturbance in the particles of the medium. Particles of the medium vibrate back and forth from their resting positions creating a series of compressions and rarefactions. The energy of the wave is transferred as particles collide. … Waves carry energy, not matter.
Which of these does sound travel fastest through?
Sound waves can be described by the wavelength and frequency of the waves. Sound travels more quickly through solids than through liquids and gases because the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster.
What type is a sound wave?
These particle-to-particle, mechanical vibrations of sound conductance qualify sound waves as mechanical waves. Sound energy, or energy associated with the vibrations created by a vibrating source, requires a medium to travel, which makes sound energy a mechanical wave.
What are the three characteristics of sound?
The three characteristics of sound are (i) Loudness, (ii) Pitch and (iii) Quality or timbre. (i) Loudness. Loudness is the physiological response of the ear to the intensity of sound. It distinguishes between a loud sound and low sound.
What are 3 ways you can make sound?
How can we produce sound give three examples?
What are the 7 properties of sound?
Does higher frequency mean louder sound?
You might suspect, that the higher the frequency, the louder we perceive a noise, but frequency does not tell us how loud a sound is. Intensity or loudness is the amount of energy of a vibration and is measured in decibels (dB). If a sound is loud, it has a high intensity.
Who discovered sound waves?
The modern study of waves and acoustics is said to have originated with Galileo Galilei (1564″1642), who elevated to the level of science the study of vibrations and the correlation between pitch and frequency of the sound source.
