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

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

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

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

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