Question 368: Ray Optics

Question

The angle of incidence for a ray of light at a refracting surface of a prism is 45o. The  angle of prism is 60o. 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

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