ERICAN PHYSICS SOCIETY: Understanding Sound Waves and Their Properties

[Rostyslav]

1. Greater sound energy forms larger waves. Larger waves have:
a) higher frequency
b) greater amplitude
c) more compressions and rarefactions
d)slower speed

2.Vibrations with a frequency below 16Hz are called:
a) audible b) supersonic
c)infrasonic d) Ultrasonic

3.If you shorten a vibrating string, the pitch of the sound does what?
4. If you tighten a vibrating string, how does that effect pitch of the sound produced?

thanks
