Sort the following materials in ascending order of their respective refractive indices - Water, Glass, Air.

Correct option is B

The correct answer is (b) Air, Water, Glass.
· The materials sorted in ascending order of their refractive indices are Air, Water, Glass.
Explanation:
· Refractive Index (RI) is a measure of how much light bends when it enters a medium. A higher refractive index indicates that light bends more.
· Refractive Indices:
· Air: ~1.0003 (approximately 1)
· Water: ~1.33
· Glass: ~1.5 to 1.9 (depending on the type of glass)
Thus, the ascending order of refractive indices is: Air<Water<Glass
