Question

If a wave has a wavelength of 9 meters and a period of 0.006, what is the velocity of the wave?

Answer 1

Divide 9 by 0.006 you should get 1500

Answer 2

Answer : Velocity of the wave, v = 1500 m/s.

Explanation :

It is given that,

Wavelength of a wave,
`\lambda=9\ m`

Time period of wave,
`T=0.006\ s`

We know that the relation between the velocity, the frequency and the wavelength is given by :

`v=\\u* \lambda`

`\because\ \\u=(1)/(T)`

`v=(\lambda)/(T)`

`v=(9\ m)/(0.006\ s)`

`v=1500\ m/s`

Hence, this is the required solution.
