Question

The wavelength of vibrations produced on the surface of water is 2 cm .if the wave velocity is 16 metre per second find its frequency and time period

Answer 1

wavelength =2cm=0.02m
velocity=16m/s
f=?
t=?
velocity = wavelength ×frequency
16=0.02×f
f=16÷0.02
f=800hz
t=1/f
t=1/800
t=0.00125sec

Answer 2

Answer:

wavelength= 2cm= 0.02m

velocity= 16m/s

velocity= wavelength* frequency

16= 0.02* f

f= 16/0.02

f= 1600/2

f=800hz

t= 1/f

t= 1/800= 0.00125 sec
