Question 15 POST_UTME_UNILAG • 2024 • PHYSICS • objective

A beam of light is incident on 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?

Correct Answer A. $ \sin^{-1}\left\( \frac{n_1}{n_2} \sin\theta_i \right $

B. $ \sin^{-1}\left\( \frac{n_2}{n_1} \sin\theta_i \right $

C. $ \sin^{-1}\left\( \frac{n_1}{n_2} \cos\theta_i \right $

D. $ \sin^{-1}\left\( \frac{n_2}{n_1} \cos\theta_i \right $

Correct Answer

Correct Option:

$ \sin^{-1}\left\( \frac{n_1}{n_2} \sin\theta_i \right $
