Question

In a string the speed of wave is 10 m/s and its
frequency is 100Hz. The value of the phase different
at a distance 2.5cm will be

Answer 1

Answer:

Speed of wave (v)=10m/s

Frequecy(γ)=100Hz

Wavelength(λ)= 10/100 = 1/10 ms

2π phase is covered in 1/10m

Hence,

at distance of 2.5 m,

the phase is

(2π×0.025)/0.1 = π/2

hope this will help u.....
