Question 316: Ray Optics

Question

The angle of incidence for a ray of light at a refracting surface of a prism is 45
o
. The  angle of prism is 60
o
. If the ray suffers minimum deviation through the prism, the angle of minimum deviation and refractive index of the material of the prism respectively, are

Accepted Answer

i = $${{{\delta _m} + A} \over 2}$$
$$ \Rightarrow $$ 45
o
= $${{{\delta _m} + 60^\circ } \over 2}$$
$$ \Rightarrow $$ $${{\delta _m} = 30^\circ }$$
sin45ÃÂº = $$\mu $$sin30ÃÂº
$$ \Rightarrow $$ $${1 \over {\sqrt 2 }} = {\mu  \over 2}$$
$$ \Rightarrow $$ $$\mu $$ = $${\sqrt 2 }$$

Answer

$${45^o};\sqrt 2 $$

Answer

$${30^o};{1 \over {\sqrt 2 }}$$

Answer

$${45^o};{1 \over {\sqrt 2 }}$$

Answer

$${30^o};\sqrt 2 $$
