An fm radio station broadcasts at 85 megahertz(mhz) what is the energy of each photon in joule? use h=6.6 x 10 to the 34th js for the planckconstant

561 × 10⁻²⁸ J

Explanation:

Data provided in the question:

Frequency of broadcast, f = 85 MHz = 85 × 10⁶ Hz

Plank's constant, h = 6.6 × 10³⁴ Js

Now,

The energy of a photon is calculated as;

Energy = h × f

on substituting the respective values, we get

Energy of the photon = 6.6 × 10⁻³⁴ × 85 × 10⁶

or

The energy of photon = 561 × 10⁻²⁸ J

the correct answer is true
