Question

A glass paper weight (n=1.5) of radius 3 cm has a tiny air bubble trapped inside it. Closest distance of the bubble from the surface is 4 cm .Where will it appear when seen from other end. (from where it is farthest)?​

Answer 1

Answer:

Using the formula for refraction through curved surfaces, vN2−uN1=RN2−N1

v1−−31.5=−51−1.5

v1+0.5=0.1

v1=−0.4

v=−410=−2.5cm

Answer 2

Answer:

Explanation:

Using the formula for refraction through curved surfaces, vN2−uN1=RN2−N1

v1−−31.5=−51−1.5
