The distance between two successive minimize of a transverse wave is 3.31 m. Five crests of the
wave pass a given along the direction of travel every 13.4 s. Find the frequency of the wave.
Find the wave speed.
Solution
a) Time period of the wave is
T = 13.4 / 4.5 = 2.977 s
frequency of the wave is
f = 1 / T = 0.335 Hz
b) speed of wave is
v = 2 d / T
= 2( 3.31 m ) / 2.977 s
= 2.223 m/s
