AIEEE 2009 | Geometrical Optics Question 182 | Physics

A transparent solid cylindrical rod has a refractive index of $${2 \over {\sqrt 3 }}.$$ It is surrounded by air. A light ray is incident at the mid-point of one end of the rod as shown in the figure. AIEEE 2009 Physics - Geometrical Optics Question 172 English

AIEEE 2009 Physics - Geometrical Optics Question 172 English

The incident angle $$\theta $$ for which the light ray grazes along the wall of the rod is :

$${\sin ^{ - 1}}\left( {{\raise0.5ex\hbox{$\scriptstyle {\sqrt 3 }$} \kern-0.1em/\kern-0.15em \lower0.25ex\hbox{$\scriptstyle 2$}}} \right)$$

$${\sin ^{ - 1}}\left( {{\raise0.5ex\hbox{$\scriptstyle 2$} \kern-0.1em/\kern-0.15em \lower0.25ex\hbox{$\scriptstyle {\sqrt 3 }$}}} \right)$$

$${\sin ^{ - 1}}\left( {{1 \over {\sqrt 3 }}} \right)$$

$${\sin ^{ - 1}}\left( {{\raise0.5ex\hbox{$\scriptstyle 1$} \kern-0.1em/\kern-0.15em \lower0.25ex\hbox{$\scriptstyle 2$}}} \right)$$

The refractive index of a glass is $$1.520$$ for red light and $$1.525$$ for blue light. Let $${D_1}$$ and $${D_2}$$ be angles of minimum deviation for red and blue light respectively in a prism of this glass. Then,

$${D_1} < {D_2}$$

$${D_1} = {D_2}$$

$${D_1}$$ can be less than or greater than $${D_2}$$ depending upon the angle of prism

$${D_1} > {D_2}$$
