When a photon enters glass from air, which one of the following quantities does not change?

Options

  1. AEnergy
  2. BVelocity
  3. CWavelength
  4. DMomentum

Correct answer

A. Energy

Step-by-step solution

Energy of the photon is given by E = h v The frequency of photon does not change hence the energy does not change.
