Question

A sound wave is travelling at 330m/s cacullate the frequency of sound wave whose wave lenght is 0.75 m

Answer 1

Answer:

Frequency of sound = 440 Hz

Explanation:

let the symbol be of following be in bracket

Given :-

Speed of sound = 330 m/s ( u)

Wavelength = 0.75 m ( w)

Frequency = f Hz ( f)

We know that ,

u = f*w

f = u/w

= 330/0.75

= 440 Hz
