Question

An ornamental silvered ball 6 cm in diameter forms an image of an object 2 m in front of the ball. Locate the image.

Answer 1

Answer:

Image distance from the surface is given as

$v = \frac{6}{7} cm$

Explanation:

As we know that the diameter of curvature of the ornament is 6 cm

So radius of the surface is 3 cm

So focal length of the surface is given as

$F = \frac{R}{2} = 1.5 cm$

now we have

$\frac{1}{v} + \frac{1}{u} = \frac{1}{f}$

now we have

$\frac{1}{v} + \frac{1}{-2} = \frac{1}{1.5}$

so we have

$\frac{1}{v} = \frac{1}{2} + \frac{2}{3}$

$v = \frac{6}{7} cm$
