Question

Relate velocity of a wave, its frequency and its wavelength. Find the time period of a wave period travelling with a velocity of 350 m/s (Given its wavelength is 700 mm).

Answer 1

velocity=wavelength×frequency
time period=1/frequency
wavelength =0.7 m
velocity=350
frequency=350/0.7=500hz
time period=1/500=0.002sec
