Question

a beam of light strikes an air/water surface. water has an index of refraction of 1.33. the angle of incidence is 48.0 degrees. what is the angle of reflection?
48.0 degrees
0.593 degrees
138 degrees
93.0 degrees

Explanation:

Step1: Recall the law of reflection

The law of reflection states that the angle of reflection \( \theta_{r} \) is equal to the angle of incidence \( \theta_{i} \).

Step2: Apply the law

Given \( \theta_{i} = 48.0^{\circ} \), by the law of reflection \( \theta_{r}=\theta_{i} \).

Answer:

48.0 degrees
