ICSE Class 10 Answered

why is there no refraction when a wave enters a new medium at a 0 degree angle? Pl explain why it is?

In such case, the incident ray goes along the normal to the surface. So, the angle of inciden is zero and hence the angle of refraction is also zero. In other words,the ray which is incident normally on the interface between the two different media, propagates un deviated from one medium to other and there is no refraction.

Can the angle of refraction in denser medium be more than the critical angle for the pair of media when the light ray is travelling from rarer to denser medium?

(a) Choose the correct statement with respect to Refraction of light [1] 1. The colour always changes when light enters from one optical medium to another. 2. Absorption of light when it strikes the surface of a medium is refraction. 3. Speed of light changes when it enters from one optical medium to another of different optical density. 4. Speed of light does not change when it enters from one optical medium to another of different optical density.
