Question
20waves passes throw a point in 2sec . If the distance between the crest and the adjacent troughs is 1.5 m calculate the frequency, wavelength and velocity.
20waves passes throw a point in 2sec . If the distance between the crest and the adjacent troughs is 1.5 m calculate the frequency, wavelength and velocity.
Open in App
Solution
wavelength=distance between the crest and the adjacent troughs= 1.5m
frequency =no.of oscillations/second =20/2 =10 Hz
velocity = frequency * wavelength = 1.5 *10
=15 m/s
frequency =no.of oscillations/second =20/2 =10 Hz
velocity = frequency * wavelength = 1.5 *10
=15 m/s
