Physics - Geometrical Optics Question with Solution | TestHub

(A) $\to$ since ${\mu }_1<{\mu }_2$, the ray of light will bend towards normal after first refraction. (B) $\to {\mu }_1>{\mu }_2$, the ray of light will bend away from the normal after first refraction. (C) $\to$ since ${\mu }_2={\mu }_3$ means in second refraction there will be no change in the path of ray of light. (D) $\to$ Since ${\mu }_2>{\mu }_3$, ray of light will bend away from the normal after second refraction. Therefore the correct options are as under. (A) $\to$ P, R (B) $\to$ Q, S, T (C) $\to$ P, R, T (D) $\to$ Q, $S$
