Question

A beam of light strikes a glass sphere of diameter `15 cm` convering towards a point `30 cm` behind the pole of the spherical surface. Find the position of the image, if `mu` of glass is `1.5`.

Answer 1

Correct Answer - `15 cm` from the pole
Fig. Here, `u = + 30 cm, v = ?`,
`mu_1 = 1, mu_2 = 1.5, R = + 15//2 cm` Use formula for refraction from rarer to denser medium.
Solve to get `v = 15 cm`.
