An electric vibrator produces ripples in a ripple tank,such that distance between one crest and one trough is 4 cm if the vibrations are produced at a rate of 4800 per minute calculate the time period and wave velocity
The distance between crests and trough is 4 cm
Vibrations are produced at rate of 4800 per minute or
=> wavelength (L) = 4cm
Vibrations are produced at rate of 4800 per minute or
or 4800 per 60 sec.
> wave velocity = distance/time = 4800/60 sec = 80 cm/s
> wave velocity = distance/time = 4800/60 sec = 80 cm/s
velocity = frequency × wavelength
=> frequency = velocity / wavelength
=> frequency = 80/4 = 20 Hz
Time period = 1/frequency
1/80 = 0.0125 Hz-1
