Question

Consider light energy that is momentarily absorbed in glass and then re-emitted. Compared to the absorbed light, the frequency of the re-emitted light is?

Answer 1

The frequency of the re-emitted light is identical to that of the absorbed light.

To find the answer, we need to know more about the frequency of light.

Why the re-emitted light has the same frequency?

• The wavelength of the light that is momentarily absorbed in glass and then re-emitted is the same, which explains why the re-emitted light has the same frequency as the absorbed light and the frequency of the absorbed light is the same.
• An electromagnetic wave's energy is inversely related to its frequency.
• The relationship between the wave's wavelength and frequency depends on the speed of light:

                              $frequency=\frac{c}{wave length}$ , c is the speed of light.

• Despite not having mass, light still has energy, and that energy is conserved.
• As a result, in order for there to be energy conservation, the energy of the light that is received and reemitted must be equal.

Thus, we can conclude that, the re-emitted light's frequency matches the absorbed light's frequency.
