Question 25 POST_UTME_IMS_U • 2018 • PHYSICS • objective

A beam of light passes through a prism of angle $\theta$ and is re\fracted at an angle $\phi$. Find the angle of deviation $\delta$ u\sing the formula $\delta = \theta + \phi - \arc\sin \left$ \frac{\sin \theta}{n} \right $$, where $n$ is the re\fractive index of the prism.

A. \delta = \theta + \phi - \arc\sin \left$ \frac{n \sin \theta}{n + 1} \right $

B. \delta = \theta + \phi - \arc\sin \left$ \frac{n \sin \theta}{n - 1} \right $

C. \delta = \theta + \phi - \arc\sin \left$ \frac{\sin \theta}{n + 1} \right $

D. \delta = \theta + \phi - \arc\sin \left$ \frac{\sin \theta}{n - 1} \right $
