Question 22 POST_UTME_IMS_U • 2018 • PHYSICS • objective

A beam of light passes from air into a glass of re\fractive index $n$. If the angle of incidence is $\theta_i$, find the angle of re\fraction $\theta_r$ u\sing Snell's law.

Correct Answer A. \theta_r = \arc\sin \left$ \frac{n_1 \sin \theta_i}{n_2} \right $

B. \theta_r = \arc\sin \left$ \frac{n_2 \sin \theta_i}{n_1} \right $

C. \theta_r = \arc\sin \left$ \frac{n_1 \sin \theta_i}{n_1 + n_2} \right $

D. \theta_r = \arc\sin \left$ \frac{n_2 \sin \theta_i}{n_1 + n_2} \right $

Correct Answer

Correct Option:

\theta_r = \arc\sin \left$ \frac{n_1 \sin \theta_i}{n_2} \right $
