Question

if speed of sound is 330 m/s and wavelength is 1.5cm find frequency

Answer 1

As we knmow that, speed of sound = wavelength* frequency

              ∴        frequency= speed of sound / wavelength

                                       = 33000/1.5

                                      = 22000 heartz

                    

Answer 2

Given
Speed=330m/s
Wavelength =1.5cm or0.015m

To find
Frequency
Solution
Speed of sound wave=frequency ×wavelength
330=frequency ×0.015
Frequency =330/0.015
=22,000 Hz
