Question

What is the index of refraction for a medium where light has a velocity of 1.75 x108 m/s?5.750.5771.731.25

Answer 1

The index of refraction is given by:

`n=(c)/(v)`

where c is the speed of light and v is the velocity of light on the medium. We know that the speed of light is 3e8 m/s and that the velocity of light in the medium is 1.75e8 m/s then we have:

`\begin{gathered} n=(3*10^8)/(1.75*10^8) \\ n=1.71 \end{gathered}`

Therefore, the index of refraction is 1.71
