MHT CET 2024 10th May Morning Shift | Ray Optics Question 18 | Physics

A ray of light is incident on a medium of refractive index ' $\mu$ ' at an angle of incidence ' $i$ '. On refraction in the medium ' $\delta$ ' is the angle of deviation. Then

$\frac{1}{\mu}=\cos \delta-\frac{\sin \delta}{\tan i}$

$\frac{1}{\mu}=\sin \delta-\frac{\cos \delta}{\tan i}$

$\frac{1}{\mu}=\cos \delta-\sin \delta \cdot \tan i$.

$\frac{1}{\mu}=\sin \delta-\cos \delta \cdot \tan i$
