Post Utme Nile University 2023 Physics Objective / Multiple Choice
Question 6 POST_UTME_NILE_UNIVERSITY • 2023 • PHYSICS • objective

A light ray passes from air into a glass slab of thickness $t$ and re\fractive index $n$. If the angle of incidence is $\theta_i$, what is the angle of re\fraction $\theta_r$?

Answer Options

Correct Answer A. \( \sin \theta_r = \frac{\sin \theta_i}{n} \)
B. \( \sin \theta_r = \frac{n \sin \theta_i}{n} \)
C. \( \sin \theta_r = \frac{\sin \theta_i}{\sin \theta_i + \frac{t}{n}} \)
D. \( \sin \theta_r = \frac{\sin \theta_i}{\sin \theta_i - \frac{t}{n}} \)
Correct Answer
A
Correct Option:
\( \sin \theta_r = \frac{\sin \theta_i}{n} \)
