Which best explains the relationship between the speed of sound and the medium through which it passes?
sound travels faster in solids because of the increased distance between solid particles
sounds travels faster in air because of the decreased distance between air particles
sound travels slower in air because of the increased distance between air particles
sound travels slower in solids because of the decreased distance between solid particles
When you speak to a friend on the telephone, the vibrations caused by your voice are:
recorded as small pits on the surface of a plastic disc
transmitted directly as sound waves to the other person
transmitted by the vibrations of the telephone wire
converted into electrical signals and sent through wires
How is frequency related to pitch?
the higher the frequency of the sound wave, the higher pitched the sound
the higher the frequency of the sound wave, the lower pitched the sound
the lower the frequency of the sound wave, the higher pitched the sound
there is no relationship between frequency and pitch
What unit is used to describe the frequency of a wave?
decibel
meters per second
hertz
wavelength
An echo is the result of a
reflected sound wave
refracted sound wave
diffracted sound wave
dispersed sound wave.
