Solution
The correct option is C frequency
When a ray of light passes from medium 1 to medium 2 there is a change in wavelength, intensity and speed, but the frequency does not change.
Reason:
Light is an electromagnetic wave wherein the electric and magnetic components of the wave are in phase and share their energy.
When light travels from one medium to another there is a change in speed of the wave and in order to maintain the same energy at both the mediums, the frequency is maintained.
