[@kunjagrawal9710]

Sir can you gave me the answer of the question.... 18. Mentioned below are laws of refraction. There is a mistake in these laws. Find it. A (i) The incident ray, refracted ray and normal to the surface separating two medias at the point of incidence, all lie in the same plane. (0) (ii) The ratio of sine angle of incidence to the sine angle of refraction remains constant. (A) In (i), instead of same plane it should be different planes. (B) In (ii) the ratio remains constant only in certain situations. (C) In (ii) the ratio is available in all situations. (D) In (i) it should be 'point of refraction' rather than 'point of incidence'.
