Question

The speed of light in leaded glass is 1.66 x 108. What is the index of refraction of this type of glass?

Answer 1

Explanation:

Speed of light in leaded glass v =1.66 x 108 mIs

Speed of light in vacuumc = 3M0 x 108 m/s

Required

Index of refraction of leaded glass ri =?

Analysis and Solution

The correct equation is n =

V

Substitute the values and their units, and solve the problem.

C

V

— 3.00 x 108 rn/s

l.6x10 8rn/s

=1.81

The index of refraction of leaded glass is about 1.81.
