Answer 1

Complete Question

Index of refraction is defined as the speed of light in a vacuum divided by the speed of light in the medium. What is the index of refraction for a glass sample? Speed of light in a vacuum c = 3.0 x 108 m/s. Speed of light in the glass = 1.50 x 108 m/s.

Answer:

The index of refraction is
`n_g = 2`

Step-by-step explanation:

From the question we are told that

The speed of light in a vacuum is
`c = 3.0 *10^(8) \ m/s`

The speed of the in the glass is
`c_g = 1.50 *10^(8) \ m/s`

From the question the index of refraction for a glass is mathematically evaluated as

`n_g = (c)/(c_g )`

`n_g = (3.0 *10^(8))/(1.50 *10^(8) )`

`n_g = 2`
