When a photon enters glass from air, which one of the following quantities does not change?
- A Energy
- B Velocity
- C Wavelength
- D Momentum
Answer & Solution
Correct Answer
(A) Energy
Step-by-step Solution
Detailed explanation
Energy of the photon is given by
\(
\mathrm{E}=\mathrm{h} v
\)
The frequency of photon does not change hence the energy does not change.
\(
\mathrm{E}=\mathrm{h} v
\)
The frequency of photon does not change hence the energy does not change.
