Question

A sound source sends waves of $400 H z$ . It produces waves of wavelength $2.5 m$ . The velocity of sound waves is:
1000

Open in App

Solution

The correct option is A 1000
Frequency is the number of waves produced per second and wavelength is distance between two consecutive compressions or rarefactions.
Velocity of wave, $v = μ \times λ$
So, velocity $v$ = $400 \times 2.5$
$v = 1000 m s^{- 1}$
