Question

A sound wave has a frequency of 342 m/s and a wavelength of 2.15 meters. What is the speed of this wave.

Answer 1

Given,

frequency(f)=342Hz

wavelength= 2.15m

Velocity(v)=?

Now,

. We know,

velocity= frequency × wavelength

or, v=342×2.15

or, v =735.3m/

Therefore, the required velocity is 735.3m/s.
