(B) From the graph,the slope is given by $	ext{slope} = 	an \left( \frac{2\pi}{10} ight) = 	an(36^o) = \frac{\sin r}{\sin i}$.Given that $	an 36^o \approx \frac{3}{4}$,we have $\frac{\sin r}{\sin i} = \frac{3}{4}$.According to Snell's Law,the refractive index of medium $2$ with respect to medium $1$ is $_1\mu_2 = \frac{\sin i}{\sin r} = \frac{1}{	ext{slope}} = \frac{4}{3}$.Since $_1\mu_2 = \frac{\mu_2}{\mu_1} = \frac{4}{3}$,it implies $\mu_2 = \frac{4}{3}\mu_1$,which means $\mu_2 > \mu_1$.Total internal reflection occurs only when light travels from a denser medium to a rarer medium. Since light is traveling from a rarer medium $(1)$ to a denser medium $(2)$,total internal reflection cannot occur.

The graph between the sine of the angle of refraction $(\sin r)$ in medium $2$ and the sine of the angle of incidence $(\sin i)$ in medium $1$ is shown below. Based on this,which of the following statements is correct? (Given: $\tan 36^o \approx \frac{3}{4}$)

$A$ ray of light passes from a denser medium to a rarer medium at an angle of incidence $i$. The reflected and refracted rays make an angle of $90^{\circ}$ with each other. The angles of reflection and refraction are respectively $r$ and $r^{\prime}$. The critical angle is given by:

$A$ glass prism of refractive index $1.5$ is immersed in water (refractive index $4/3$) as shown in the figure. $A$ light beam incident normally on face $AB$ undergoes total internal reflection at face $BC$.

The critical angle is $\theta$ for light going from medium $P$ to medium $Q$. If the speed of light in medium $P$ is $V_{P}$,then the speed of light in medium $Q$ is:

The critical angle of light passing from glass to air is minimum for:
