Question

In a sinusoidal wave the time required for a particular point to move from equilibrium position to maximum displacement is `0.17s`, then the frequency of wave is:
A. `1.47Hz`
B. `0.36Hz`
C. `0.73Hz`
D. `2.94Hz`

Answer 1

Correct Answer - A
`T=4xx` time from max. displacemetn to zero displacement `=4xx0.170=0.68s`
`v=(1)/(T)=(1)/(0.68)=1.47Hz`
