A light ray travels from optically denser medium to optically rarer medium, if t
A light ray travels from optically denser medium to optically rarer medium, if the angle of incidence and refraction at point of incidence are \( \angle i \) and \( \angle \boldsymbol{r} \) respectively, then find the angle of deviation in terms of \( \angle i \) and \( \angle r \)
- A. \( \angle i+\angle r \)
- B. \( \frac{L}{L r} \)
- C. \( \angle i-\angle r \)
- D. \( \angle r-\angle i \)
Step-by-step solution
When light travels from a denser to a rarer medium, it bends away from the normal, so the angle of refraction (r) is greater than the angle of incidence (i). The angle of deviation is the angle between the incident ray and the refracted ray, which in this case is r - i.
