Which of the following change is observed when light travels from air to glass ?
- A speed of light only
- B frequency of light only
- C wavelength of light only
- D wavelength and speed of light only
Answer & Solution
Correct Answer
(D) wavelength and speed of light only
Step-by-step Solution
Detailed explanation
When light enters a denser medium like glass, its speed decreases and its wavelength shortens proportionally. However, the frequency remains constant because it is determined solely by the source of the light. D) wavelength and speed of light only
