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

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

Explanation :

It is given that,

Wavelength of a wave,  

Time period of wave,

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

Hence, this is the required solution.

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.
