Question

A vibrating body produce a wave of a wavelength 2.5 m in a medium where the wave travels with a velocity of 1250 metre per second. find the period of vibrating of the wave

Answer 1

hope u understand the calculations yourself

Answer 2

Answer:

The time period of the wave is $T=2\times 10^{-3}\ s$

Explanation:

The wave length of the wave is $\lambda =2.5\ m$

The velocity of the wave is v=1250 m/s

We know that

$v=\nu \lambda\\\nu=\dfrac{v}{\lambda}\\\nu=\dfrac{1250}{2.5}\\\nu=500$

For the time period of the wave we know that,

$\nu=\dfrac{1}{T}\\T=\dfrac{1}{\nu}\\T=\dfrac{1}{500}\\T=2\times 10^{-3}\ s$
