Question

The distance between consecutive crest and trough of a wave is 10 cm. If the speed of wave is 200 cm/s. Then the time period of wave is

Answer 1

Given;

λ=10cm(wavelength)

V=200cm/s

and the equation is

V=fλ

200=f*10

=>f=20 vibrations/second

time period=i/f

=>1/20

=0.05 sec

hoped this helped.
