Question

Wave of frequency 150 words are produced in a string find the wavelength amplitude and phase velocity of wave in si unit

Answer 1

a)

Frequency f is reciprocal of time period T

f=1/T

So

T=1/f

As f=150Hz

T=1/150Hs

T=0.00667 second

(b)

Wavelength is equal to

Wavelength=v/f

Where v is speed and f is frequency of the waves.

(c)

Speed v is

v=wavelength×f
