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 [tex]n_g = 2[/tex]
Explanation:
From the question we are told that
The speed of light in a vacuum is [tex]c = 3.0 *10^{8} \ m/s[/tex]
The speed of the in the glass is [tex]c_g = 1.50 *10^{8} \ m/s[/tex]
From the question the index of refraction for a glass is mathematically evaluated as
[tex]n_g = \frac{c}{c_g }[/tex]
[tex]n_g = \frac{3.0 *10^{8}}{1.50 *10^{8} }[/tex]
[tex]n_g = 2[/tex]
