Statement-1: In interference experiment, the fringe system will shift, if a glass plate is interposed in the path of the one of the interfering beams and the shift will be on the side of the glass plate.
Statement-2: The velocity of light in glass is smaller than in air.
Statement-2: The velocity of light in glass is smaller than in air.
View answer and explanation
Correct option: A
Statement-1 is true, Statement-2 is true, Statement-2 is the correct explanation for Statement-1
Option A is correct. Statement-1 is true because the introduction of a glass plate shifts the fringe system. Statement-2 is true because light travels slower in glass than in air, and it is the correct explanation for the shift.
