Wave Basics & Properties of Sound

The number of waves counted by an observer on the sea-coast in one minute is 54. If the wavelength of the waves is $5$ m then the velocity of the waves in m/s will be

Show answer and solution

Answer: (a)

Frequency $n = \frac{54}{60} = 0.9$ Hz
$v = n\lambda = 0.9 \times 5 = 4.5$ m/s
So the answer is (a) $4.5$ m/s.
