1.	One face of a glass cube of side 0.06 m is silvered. An object is placed at a distance of 0.07 m from the face opposite to the silvered face. Looking from the object side, the image of the object appears to be 0.11 m behind the silvered face. The refractive index of material of glass is :–(a) 1.5 (b) 1.3 (c) 0.4 (d) ∞
Answer» Correct Option (a) 1.5 Explanation: It is clear from figure that 0.07 + y = 0.11 y = 0.04 μ = 0.06/0.04 = 1.5

One face of a glass cube of side 0.06 m is silvered. An object is placed at a distance of 0.07 m from the face opposite to the silvered face. Looking from the object side, the image of the object appears to be 0.11 m behind the silvered face. The refractive index of material of glass is :–(a) 1.5 (b) 1.3 (c) 0.4 (d) ∞

Answer»

Correct Option (a) 1.5

Explanation:

It is clear from figure that

0.07 + y = 0.11

y = 0.04

μ = 0.06/0.04 = 1.5
