Question

Theh wavelength of waves produced on surface of water is 20 cm. If the wave velocity is 24 m s-1, calculate :
1)The Number of waves produced in one second, and 2) the time in which one wave is produced.

Answer 1

Given wavelength(lamda)=20cm=0.2m
wave velocity(v)=24m/s
1)No.of waves produced in one second
in any wave frequency is equal to no.of waves
from the equation v=lamda*frequency
hence,f=v/lamda
f=24/0.2
=120
2)time=1/f
           =1/120
           =0.008
