Answer:
[tex]E=4.61\times 10^{-28}\ J[/tex]
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,
[tex]E=6.63\times 10^{-34}\times 696000\\\\=4.61\times 10^{-28}\ J[/tex]
So, the energy of the wave is equal to[tex]4.61\times 10^{-28}\ J[/tex].
