AP EAMCET · PHYSICS · Ray Optics
A ray of light travels from an optically denser to rarer medium. The critical angle for the two media is ' \(C\) '. The maximum possible deviation of the ray will be
- A \(\frac{\pi}{2}-C\)
- B \(2 C\)
- C \(\pi-2 C\)
- D \(\pi-C\)
Answer & Solution
Correct Answer
(C) \(\pi-2 C\)
Step-by-step Solution
Detailed explanation
The deviation is given by \(\begin{aligned} & \delta=\pi-2 \mathrm{i} \\ & \text { At } \mathrm{i}=\mathrm{C}, \delta=\delta_{\max } \\ & \therefore \quad \delta_{\max }=\pi-2 \mathrm{c} \end{aligned}\)
