As light travels from air to another medium, the incident angle is [tex]30.0^\circ[/tex], and it refracts at [tex]22.0^\circ[/tex]. What is the index of refraction?

A. 0.751
B. 0.0262
C. 1.33
D. 38.2

Answer :

Final answer:

The index of refraction for air is 1.000. Using Snell's law, we can find the index of refraction for the second medium (n2) based on the given incident and refracted angles. The index of refraction for the second medium is approximately 1.33.

Explanation:

The index of refraction for air is taken to be 1.000. From the given information, the incident angle is 30.0° and the angle of refraction is 22.0°. Using Snell's law, we can find the index of refraction for the second medium (n2).

Snell's law can be written as: n1 * sin(incident angle) = n2 * sin(refracted angle)

Substituting the known values: 1 * sin(30.0°) = n2 * sin(22.0°)

Therefore, the index of refraction for the second medium (n2) is approximately 1.33.
