When light travels from a rarer medium to a denser medium, what happens to its frequency?
- A.It increases
- B.It decreases
- C.It remains unchanged
- D.It becomes zero
Show correct answer & step-by-step solution
Correct answer: C — It remains unchanged
Solution
The frequency of a light wave is a characteristic of the source and does not change when the light passes from one medium to another. Only the speed and wavelength of the light change.
