Question

a certain F.M. station broadcast at wavelength equal to 3.5 m. how many photons per second correspond to transmission of 1 killo watt​

Answer 1

Explanation:

Power = 1 killo watt = 1000 watt

energy of one photon E = hc÷L

= 6.626×10^-34×3×10^8

3.5

= 5.679×10^-26

Number of photon emitted = 1000

5.679

×10^-26

=176.08×10^26
