1
Q
What is the work done by an elastic force?
A
W = ½ kx2 = Fd/2
2
Q
What kind of waves are sound waves?
A
Transverse waves
3
Q
What is the formula for the fundamental frequency of sound?
A
f = v / 2L
v = speed
L = length
or f = c / lambda
4
Q
What is the formula for frequency?
A
f = 1 / T
T = period
