Problem

When light travels from medium 1 with refractive index n1n_1 to medium 2 with refractive index n2n_2 (n1>n2n_1>n_2), the critical angle ici_c is correctly given by (a) sin⁡ic=1n1\sin i_c = \dfrac{1}{n_1} (b) sin⁡ic=n1−n2n1\sin i_c = \dfrac{n_1-n_2}{n_1} (c) sin⁡ic=n2n1\sin i_c = \dfrac{n_2}{n_1} (d) sin⁡ic=n2n1\sin i_c = \sqrt{\dfrac{n_2}{n_1}}
