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`.

Text Solution

Verified by Experts

The correct Answer is:
`15 cm` from the pole
Here, `u = + 30 cm, v = ?`,
`mu_(1) = 1, mu_(2) = 1.5, R = + 15//2 cm`. Use formula for refraction form rarer to denser medium.

Solve to get `v = 15 cm`.
