an object that produces its own light is
luminous
an object that reflects light is
illuminated
sounds is an example of a
longitudinal wave
a detected change in frequency due to the motion of the source or the motion of the listener
doppler effect
characteristic of sound related to frequency
piton
because there are no wave particles for the sound waves to vibrate, sound will not travel through what?
