What is critical angle?
Asked by Topperlearning User | 4th Jun, 2014, 01:23: PM
Critical angle for a pair of media in contact is the angle of incidence in the denser medium corresponding to which the angle of refraction in the rarer medium is 90 degree. It depends on the nature of media in contact.
