For a certain transverse wave, the distance between two successive crests is 3.11 m, and 5 crests pass a given point along the direction of travel every 12.16 s. Calculate the wave speed.

Answer 1

Note, when 2 crests pass that is one period, three crests is two periods etc

period = 12.16/4 = 3.04 s

speed = distance/time

speed = 3.11/3.04

Answer 2

The answer seems to be wrong when I submit.
