The refraction of light ray takes place from air to water, water to glass and again glass to air. The ray emerges parallel to incident ray. The correct relation is [ n _ a , n _ w , n _ g . represent refractive indices of air, water and glass respectively.
Options
- Ag ^ n _ w = a ^ n g a ^ n w
- Bg ^ n w = a ^ n g a ^ n w
- Cw ^ n g = a ^ n w a ^ n g
- Dw ^ n g = a ^ n g a ^ n w
Correct answer
D. w ^ n g = a ^ n g a ^ n w
