Question
If the wavelength of electromagnetic radiation is doubled, what happens to the energy of photon?
Open in App
Solution
The energy of photon,
E
=
h
ν
=
h
c
λ
where
h
=
Plank's constant,
c
=
velocity of light and
λ
=
wavelength.
Thus,
E
∝
1
λ
Hence, if the wavelength is doubled, the energy of photon will be half.

Q.
The terminology of different parts of the electromagnetic spectrum is given in the text. Use the formula
E
=
h
ν
(for energy of a quantum of radiation: photon) and obtain the photon energy in units of eV for different parts of the electromagnetic spectrum. In what way are the different scales of photon energies that you obtain related to the sources of electromagnetic radiation?
