Expert Answer:

Dear student
Evrything changes except the frequency.
When light goes from one medium to another, its wavelength, speed & intensity changes. Only frequency doesnt change.
Frequency is the characteristic of the source producing the light. It corresponds to the energy carries by that electromagnetic wave. Hence it cannot change.
We hope that clarifies your doubt.
