The total energy carried by the light wave when it travels from a rarer to a non-reflecting and non-absorbing medium

Options

  1. Aremains same
  2. Bincreases
  3. Ceither increases or decreases depending upon angle of incidence
  4. Ddecreases

Correct answer

A. remains same

Step-by-step solution

When a light wave travels from a rarer medium to a non-reflecting and nonabsorbing medium, the total energy it carries remains the same. While the speed of light changes as it transitions between mediums, the energy of the light is determined by its frequency and the number of photons, which remain constant during this transition.
