A beam of light strikes a sheet of glass at an angle of 57.0 degrees with the normal in air. You observe that red light makes an angle of 38.1 degrees with the normal in the glass, while violet light makes an angle of 36.7 degrees.

What are the indexes of refraction of this glass for these colors of light?

The index of refraction for red and violet light in the glass can be calculated using Snell's law. The calculated indices of refraction for red and violet light are approximately 1.48 and 1.52 respectively.

Explanation:

The

index of refraction

can be determined by using Snell's law, which is given by the expression n1sin(θ1) = n2sin(θ2). In this case, n1 (the index of refraction of air) is approximately 1, and θ1 is the incident angle in the air (57.0 degrees).

The transmitted angles θ2 are given as 38.1 degrees for red light and 36.7 degrees for violet light. So you can calculate the indices of refraction (n2) for red and violet light in the glass by rearranging the formula to n2 = n1sin(θ1) / sin(θ2). Plugging in the respective values, you find the index of refraction for red light is approximately 1.48 and for violet light is approximately 1.52. This demonstrates that different colors of a light beam refracts at different angles in a medium due to their different wavelengths.
