Question

A local AM radio station broadcasts at a frequency of 696 KHz. Calculate the energy of the frequency at which it is broadcasting.

Answer 1

`E=4.61* 10^(-28)\ J`

Step-by-step explanation:

Given that,

The frequency of local AM radio station, f = 696 KHz = 696000 Hz

We need to find the energy of the frequency at which it is broadcasting.

We know that,

Energy of a wave, E = hf

Where

h is Planck's constant

Put all the values,

`E=6.63* 10^(-34)* 696000\\\\=4.61* 10^(-28)\ J`

So, the energy of the wave is equal to
`4.61* 10^(-28)\ J`.
