The speed of light in a medium depends on:
- A nature of the source
- B motion of the source
- C wavelength
- D intensity of the light
Answer & Solution
Correct Answer
(C) wavelength
Step-by-step Solution
Detailed explanation
In a medium, the refractive index depends on the wavelength of the light (a phenomenon called dispersion). This causes different colors of light to travel at different speeds through the same material. C) wavelength
