speed of sound quiz

One way to describe sound

vibrations travelling through a medium that can be heard

What can mechanical vibrations be transmitted through

liquid, solid, or gas, another way to describe sound

One way to describe sound

vibrations travelling through a medium that can be heard

What can mechanical vibrations be transmitted through

liquid, solid, or gas, another way to describe sound

A disturbance that moves through a medium in a form of (blank) waves

pressure, mechanical

What is sound

mechanical energy made by a thing of disturbance, moving to ears from atomic particles

how does sound travel through a medium

transfer of energy from one particle to another

Def of mechanical wave

distribution of energy through a medium by the transfer of energy from one particle to another

what way do sound energy move

outwards in all directions from the source

Without (blank) there would be no sound

energy

Without (blank) there would be no particles to carry

a medium

what are the easiest produced sound waves

longitudinal waves

compression

when particles are forced, or pressed, together

rarefraction

particles are given extra space and allowed to expand

 one compression and one rarefaction is called a

wavelength

All material substances are (blanks) which may be forced into which may be forced into (blanks) about their rest positions

comprised of atoms, vibration motion

individual particles inside of matter perform

elastic oscillations

what happens when particles of a medium are displaced from their rest positions?

internal forces cause the particles to oscillate and return to rest when disturbance is gone

attenuation

sound waves travel their intensity is reduced due to spreading, scattering, and absorption

 the speed of light is (blank) than the speed of light

slower

formula for speed of sound

frequency * wavelength (𝜆 x 𝑓)

formula for speed of sound wave

distance / time

what can sound waves not travel through?

a vacuum

order of compactness within matter greatest to least

solid, liquid, gas

density’s impact on speed

greater density of a medium the slower of speed

temperature increases speed (blank)

increases

formula for temperature

v = 331m/s + 0.6(T in Celcius)
