Question

A point source of light is placed at a distance of 25.0 cm from the center of a glass sphere of radius 10.0 cm. Find the image of the source.

the first image is at -90.0 cm, and the final image is at 28 cm. Tell me how to do it

32-8 Refraction at a Spherical Surface Example 32-13: A spherical "lens." point source of light is placed at a distance of 25.0 cm from the center of a glass sphere of radius 10.0 cm. Find the image of the source I1 Source R = 10.0 cm Copyright© 2009 Pearson Education, Inc.

Explanation / Answer

By formula

n1/do + n2/di = (n2 - n1) /R

=> 1/15 + 1.5/di = 0.5/10

=> 1.5/di = 0.5/10 - 1/15

=> di = - 90 cm    ---------> first image

Also, 1.5/105 + 1/di = 0.5/10

=> 1/di = 0.05 - 1.5/105

=> di = 28 cm       ----------> second image
