Light from a point source in air falls on a convex spherical glass surface of refractive index `1.5` and radius of curvature `20cm`. The distance of light source from the glass surface is `100cm`. At what position is the image formed ?

Explanation

To solve the problem step by step, we will use the formula for refraction at a spherical surface. The formula is given by:

\[ \frac{\mu_2}{v} - \frac{\mu_1}{u} = \frac{\mu_2 - \mu_1}{R} \]

Where:
- \(\mu_1\) = refractive index of air = 1
