Light from a point source in air falls on a spherical glass surface whose radius of curvature and refractive index are 20 cm and 1.5 respectively. If the distance of light source from the glass surface is 100 cm, then at which position image will be formed?
Text Solution
Verified by ExpertsThe correct answer is:
C
: since light goes from air (rarer medium) to glass (denser medium),
Here, 
or 
v = 100 cm
Hence, the image is formed at a distance of 100 cm from the glass surface.
