Question

# A sound wave having a wavelength of 2 cm is travelling in water. If the velocity of sound in water is 1600 m/s. Find the frequency of the sound wave.9000 Hz8000 Hz1600 Hz7000 Hz

Solution

## The correct option is B 8000 HzSpeed of a wave is given by: v=fλ where: f: Frequency λ: Wavelength 1600=f×0.02 f=8000 Hz
