During reflection of light which property
changes ?
(A) Velocity
(B) Frequency
(C) Wavelength
(D) None of the above​

Answer 1

Answer:

D IS THE RIGHT ANSWER

Explanation:

Answer 2

Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases.
