Revered Members,
When light travels from rarer to denser medium and vice versa, velocity and wavelength changes but frequency remains constant. What is the reason? This question was asked in the physics quiz competition held in my school. I replied that since energy of the light remains the same and since energy is proportional to frequency, frequency remains constant. But the convener said the answer is wrong. Am i wrong?
