Question

A body is vibrating 6000times in 1 min. If the velocity of sound in air is 360m/s. Find:
(A) frequency of vibration in hz .
(B) wave length of sound produced.

Answer 1

a) frequency of vibration in hz

Answer 2

HELLO FRIEND..

HERE IS YOUR ANSWER..

a) Frequency of vibration in hertz  

Given,  

Number of vibration in one minute = 6000  

Number of vibrations in one sec = 6000/ 60 =100 Hz  

Therefore, Frequency, f = 100 Hz  

(b) Wavelength of the wave produced  

Given,  

Velocity of speed in air, v = 360 ms^–1  

Frequency, f = 100 Hz  

Wavelength,  f V ⇒ λ= 360 ms^−1/ 100 s−1 = 3.6 m  

The wavelength of the wave is 3.6 m

HOPE IT HELPS YOU!! :)
