Question

A sound wave travels at the speed of 330 minutes if its wavelength is 1.5 CM what is the frequency of the wave​

Answer 1

Heya friend,

One correction :- We will take the speed of sound wave as 330 m/s , you have taken that in minutes probably by mistake.

Now,

v (velocity )= 330 m/s

λ (wavelength) = 1.5 cm

                        = $\frac{1.5}{100}$ m

                        = 0.015 m

ν (frequency) = ?

Now,

We know,

v = νλ

So,

ν = v / λ

  = $\frac{330}{0.015}$ Hz

  = 22000 Hz

  = 22 × $10^{3}$ Hz

 = 22 KHz

Thanks !
