Question

In a sinusoidal wave the time required for a particular point to moce from equilibrium pasition to maximum diaplacement is `0.17s`, then the frequency of wave is:
A. `1.47Hz`
B. `0.36 Hz`
C. `2.94 Hz`
D. `2.48 Hz`

Answer 1

Correct Answer - A
Maximum displacement from mean ouccers at `T/4` For a motion in SHM particel taken one-fourth periodic time to reach maximum displacement. Hence, periodic time is given by

`T= 0.17xx4= 0.68 s`
Hence, frequency `=(1)/("time period")`
`=(1)/(0.68)= 1.47 Hz`
