Question E2

1. An FM radio station broadcasts at a frequency of 98.1 MHz. The power radiated from the antenna is [tex]6.5 \times 10 \text{ W}[/tex]. How many photons per second does the antenna emit?

Answer :

Final answer:

The number of photons emitted per second by the antenna can be calculated by dividing the power emitted by the antenna by the energy of a single photon.


Explanation:

The number of photons emitted per second by the antenna can be calculated using the formula:

Number of photons emitted per second = Power emitted by the antenna / Energy of a single photon

To find the energy of a single photon, we can use the equation:

Energy of a single photon = Planck's constant x frequency

Substituting the given values into the equations, we can calculate the number of photons emitted per second.
