Let the refractive index of a denser medium with respect to rarer medium be n12 and its critical angle angle B. At an angle of incidence A when light travels from denser medium to rarer medium, a part of light is reflected and rest is refracted and the and the angle between reflected and refracted ray is 90 degree. What is relation between A and B. ? a) tan A = sin B b) sec A = cos B c) sin A = tan B d) cos A = sec B
