Wave Basics & Properties of Sound

Waves having a velocity 10m/s, strike a stationary boat near the sea shore. The distance between two consecutive crests of the waves is 40m. After how many second, the consecutive waves strike the boat?

Show answer and solution

Answer: (c)

Distance between consecutive crests is the wavelength: $\lambda = 40$ m.
Time between consecutive waves is the period: $T = \frac{\lambda}{v} = \frac{40}{10} = 4$ s
So the answer is (c) $4$ s.
