The distance between two successive crests of

a certain transverse wave is 1.12 m. Eight
crests pass a given point along the direction
of travel every 12.3 s.
Calculate the wave speed.
Answer in units of m/s

3 answers

The frequency of waves going by is
f = 8/12.3 = 0.6504 s^-1

The wavelength is L = 1.12 m

The wave speed is
V = f*L = _____ m/s
V=0.73m/s
correct
