The critical angle of incidence $i_c$ for a ray incident from a denser to rarer medium, is that angle for which |
the angle of reflection is 90° the angle of refraction is 90° the angle of refraction is 0° the angle of reflection is 0° |
the angle of refraction is 90° |
The correct answer is Option (2) → the angle of refraction is 90° |
