If the speed of light in carbon disulfide and vacuum is X and Y respectively, then
- A. X<Y ✓
- B. X>Y
- C. X\ge Y
- D. X=Y
Correct Answer: A. X<Y
Explanation
The speed of light is maximum in a vacuum. Therefore, the speed of light in any medium like carbon disulfide (X) will always be less than its speed in a vacuum (Y).
