Question

A sheet of glass has nred =1.52 and nviolet =1.55 . a narrow beam of white light is incident on the glass at 33.0 �� . What is the angle of refraction for the red light?

1) 30.0 ��
2) 31.0 ��
3) 32.0 ��
4) 34.0 ��

Answer 1

The angle of refraction for red light is approximately 31.0°.

Step-by-step explanation:

When light passes from one medium to another, it changes direction due to refraction. The angle of refraction can be calculated using Snell's Law, which states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the speeds of light in the two media.

In this case, the angle of incidence is 33.0° and the indices of refraction for red and violet light are 1.52 and 1.55, respectively. Using Snell's Law, we can calculate the angle of refraction for red light as:

sin(33°) / sin(angle of refraction for red light) = 1.52 / 1.00

Solving for the angle of refraction for red light, we find that it is approximately 31.0°. Therefore, the correct answer is 2) 31.0°.
