Question

Two transparent media of refractive indices ${\mu }_1$ and ${\mu }_3$ have a solid lens shaped transparent material of refractive index ${\mu }_2$ between them as shown in figures in Column II. A ray traversing these media is also shown in the figures. In Column I different relationship between ${\mu }_1,{\mu }_2$ and ${\mu }_3$ are given. Match them to the ray diagram shown in Column II.

Answer 1

(A) ${\mu }_1<{\mu }_2$

Since there are multiple systems & combination given.SO if ${\mu }_1<{\mu }_2$,Then convex surface will behave converging & concave surface will behave diverging at that interface ,which can be observed in 1&3.

(B) ${\mu }_1>{\mu }_2$

if ${\mu }_1>{\mu }_2$ then convex surface will behave diverging & concave surface will coverge the rays which can be observed 2,4,5

(C) If ${\mu }_2={\mu }_3$, then there will be no deviation in the light ray.At the interface of ${\mu }_2\&{\mu }_3$.Which can be observed in 1,3 &5.

(D)If ${\mu }_2>{\mu }_3$ then convex surface will behave converging & concave surface will behave diverging.
