Question

A marine weather station detects waves which are 8.0 meters long and 1.65 meters high and travel 4 meters each second. Determine the frequency of these waves.

Answer 1

Gien:
Wave length, λ = 8.0 m
Amplitude, A = 1.65 m
Velocity, v = 4 m/s

By definition,
v = fλ
where f =  the frequenct.

Therefore
f = v/λ
  = (4 m/s)/(8 m)
  = 0.5 Hz

Answer: The frequency is  0.5 Hz.
