## Question

In a sinusoidal wave, the time required for a particular point to move from maximum displacement to zero displacement is 0.17s. The frequency of the wave is

### Solution

1.47 Hz

Time required to move from maximum displacement to zero displacement is *T*/4. Thus *T* = 4× 0.17 = 0.68 s.
