A photon of light enters a block of glass after travelling through a vacuum. The energy of the photon on entering the glass block

Question

A photon of light enters a block of glass after travelling through a vacuum. The energy of the photon on entering the glass block (A) Increases because its associated wavelength decreases (B) Decreases because the speed of the radiation decreases (C) Stays the same because the speed of the radiation and the associated wavelength do not change (D) Stays the same because the frequency of the radiation does not change

Frequency of light does not change with medium, it is the property of the wave from wave source and the energy of a photon is given by E=hν . Here, ν is the frequency.

Q. A photon of light enters a block of glass after travelling through a vacuum. The energy of the photon on entering the glass block

Increases because its associated wavelength decreases

Decreases because the speed of the radiation decreases

Stays the same because the speed of the radiation and the associated wavelength do not change

Stays the same because the frequency of the radiation does not change

Frequency of light does not change with medium, it is the property of the wave from wave source and the energy of a photon is given by $E = h ν$ . Here, $ν$ is the frequency.
