ICSE Class 10 Answered

(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.

Expert Answer
Correct Statement :-
 
(3) Speed of light chages when light travel from one transparent medium to
another transparent medium of different optical density.
 
----------------------------------------------------------------------
(1) Colour does not change when light travels from one medium to another .
 
(2) Absorption is not taking place in refraction , only light ray deviates from its initial path.
