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

Sagot :

The index of refraction is given by:

[tex]n=\frac{c}{v}[/tex]

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:

[tex]\begin{gathered} n=\frac{3\times10^8}{1.75\times10^8} \\ n=1.71 \end{gathered}[/tex]

Therefore, the index of refraction is 1.71
