A light ray enters a glass slab at exactly 90⁰. Its angle of refraction is​

Answer»

When the angle of incidence in water reaches a CERTAIN CRITICAL value, the REFRACTED ray lies along the BOUNDARY, having an angle of refraction of 90-degrees. This angle of incidence is KNOWN as the critical angle; it is the largest angle of incidence for which refraction can still occur.angle of refraction is zero.Explanation:
