Energy is the ability to do work
Nope......... Constant speed but change in direction can cause acceleration which would give a finite force........
Answer
given,
difference between the two consecutive maximum
λ = 0.870 - 0.540
λ = 0.33 m
speed of sound = 340 m/s
b) frequency of the sound
v = f x λ
340 = f x 0.33

f = 1030.3 Hz
a) phase difference
the expression of phase difference is given by




now,
