Question

in a transverse wave the separation between a crest and its nearest trough is 5 centimetre and its time period is 0.001 second calculate wavelength of the wave, frequency of the wave,wave velocity

Answer 1

difference between crest and trough is wavelength =5cm
T=0 .001sec
so use formula velocity=wavelength/time
velocity=50m/sec
frequency=1/time period
=1/(0.001)=1000Hz
