Question

When a ray of light strikes the surface of separation of two optical media .......... it does not suffer any refraction.

• A. normally
• B. at acute angle
• C. at obtuse angle
• D. None of the above

Answer 1

The correct option is A normally

When the ray of light strikes normally, its angle of incidence is 0 and hence angle of refraction will also be 0 i.e. no deviation. hence correct option is A.
