Light from a point source in air falls on a spherical glass surface. If `mu = 1.5`, and radius of curvature `= 20 cm`, the distance of light source from the glass surface is `100 cm` , at what position will the image be formed ? (NCERT Solved Example)

A

50cm

B

100cm

C

125cm

D

25cm

Text Solution

Verified by Experts

The correct Answer is:
B

`mu_(2)/v - mu_(3)/u=(mu_(2)-mu_(1))/R,1.5/v- 1/(-100)=(1.5-1)/((20))`
