An image is formed at a distance of $100 cm$ from a glass surface with refractive index $1.5$ when a point object is placed in the air at a distance of $100 cm$ from the glass surface. What is the radius of curvature is of the surface?

Options:

Answer:

Solution:

$\frac{μ_{2}}{V} - \frac{μ_{1}}{U} = \frac{μ_{2} - μ_{1}}{R}$

$\frac{1.5}{100} + \frac{1}{100} = \frac{1.5 - 1}{R}$

$R = 20 cm$
