Question:
When a ray of light moves from one medium to another medium,
When a ray of light moves from one medium to another medium,
Show Hint
Frequency never changes during refraction.
Updated On: Apr 21, 2026
- its frequency alone changes
- its frequency alone remains unchanged
- its wavelength remains unchanged
- both its frequency and wavelength change
- its velocity remains constant
Show Solution
Verified By Collegedunia
