Question

the frequency of the wave is 40 hertz and its value length is 8 M find the velocity of the wave

Answer 1

I think the question is that:

The frequency of the wave is 40 hertz and its wave length is 8 m find the velocity of the wave:

Since wave speed = Wavelength * frequency

= 40* 8 m/s

= 320m/s.

Hope it's helpful to u.

Answer 2

velocity of wave= 5 it is the answer
