The speed of propagation of light wave in a dispersive medium does NOT depend on the :
- A wave length of light
- B refractive index of the medium
- C intensity of light
- D frequency of light
Answer & Solution
Correct Answer
(C) intensity of light
Step-by-step Solution
Detailed explanation
In a dispersive medium, the refractive index changes with the wavelength and frequency, which directly affects the wave's speed. However, intensity (the brightness or amount of energy) does not change how fast a light wave travels through the material. C) intensity of light
