Typical frequencies for several types of electromagnetic radiation are given below. Calculate the energy of each type of radiation.

a. A gamma ray: ν = 1.64 ✕ 10^20 s^−1
b. A microwave: ν = 4.95 ✕ 10^10 s^−1
c. An AM radio wave: ν = 2.00 ✕ 10^6 s^−1

Explanation:

The energy of electromagnetic radiation is given by :

[tex]E=h\nu[/tex]

Where, h is the Planck's constant

(a) A gamma ray, [tex]\nu = 1.64\times 10^{20}\ Hz[/tex]

Energy,

[tex]E=6.63\times 10^{-34}\times 1.64\times 10^{20}\\E=1.08\times 10^{-13}\ J[/tex]

(b) A microwave, [tex]\nu = 4.95\times 10^{10}\ Hz[/tex]

Energy,

[tex]E=6.63\times 10^{-34}\times 4.95\times 10^{10}\\E=3.28\times 10^{-23}\ J[/tex]

(c) A AM radio wave, [tex]\nu = 2\times 10^{6}\ Hz[/tex]

Energy,

[tex]E=6.63\times 10^{-34}\times 2\times 10^{6}\\E=1.32\times 10^{-27}\ J[/tex]

Therefore, this is the required solution.
