A ray of light, travelling in medium $A$ , is incident on the plane interface of two medium $A$ and $B$ and gets refracted into the medium $B$ . The angle of incidence is $i$ and that of refraction is $r$ . The graph between $\sin (i)$ and $\sin (r)$ is as shown in the diagram. The correct statement among the following is

Options:

Answer:

Solution:

$\frac{sin i}{sin r} = cot 37 = \frac{4}{3} = \frac{V_{A}}{V_{B}}$

as going from rarer to denser no TIR can take place

$\frac{μ_{B}}{μ_{A}} > 1 \Rightarrow μ_{B} > μ_{A}$
