A ray of light passes from vaccum into a medium of refractive index n. If the angle of incidence is twice the angle of refraction, then the angle of incidence isA. `cos^-1(n//2)`B. `sin^-1(n//2)`C. `2cos^-1(n//2)`D. `2 sin^-1(n//2)` |
|
Answer» Correct Answer - C `n=sini/(sin(i//2))=(2sin(i//2)cos(i//2))/sin(i//2)` Solving we get, `i=2 cos^-1(n//2)` |
