Question

a wave propagating along a string is described by the equation y(x,t)=0.04sin(40x-5t) in which the numerical constants are in their respective S.I units.The wavelength of the wave will be ?​

Answer 1

Answer:

A wave travelling along a string is described by the equation :

......(1)

To find,

Wavelength of wave.

Solution,

The general equation of wave travelling along a string is given by :

.....(2)

On comparing equation (1) and (2) we get :

k = 40 rad/m

Since,
