A) wave theory of light
B) corpuscular theory of light
C) both (a) and (b)
D) neither nor
Correct Answer: A
Solution :
Due to wave particle duality of matter, light simultaneously exhibits properties of both waves and particles. When it undergoes refraction say from air to glass, then there is a change in direction of wave due to a change in its velocity. Refraction of light wave occurs at the boundary of air-glass medium at the boundary between the two media the waves phase velocity is altered, its changes direction and its velocity decreases but frequency remains unaltered.You need to login to perform this action.
