Answer:
156AM
Explanation:
The energy of a photon can be calculated using Planck-Einstein relation:
E = h x f
where,
E is the energy of the photon
h is Planck's constant (6.626 . 10⁻³⁴ J . s)
f is the frequency associated to the photon
Energy = h(planck's constant) x frequency
so, to get the final answer we just have to divide the given two frequencies.
=> (90.9 x 10^6)/(586 x 10^3)
= 155.811
≅ 156
so 156 AM photons are required to have the energy of a FM photon.
