QNEET-2016-Ph-1087: NEET 2016 Physics - Class 12 NEET-2016-Ph-1087 Solution: The angle of incidence for a ray of light at a refracting…

The angle of incidence for a ray of light at a refracting surface of a prism is 45∘45^\circ. The angle of prism is 60∘60^\circ. 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∘;245^\circ; \sqrt{2} 30∘;230^\circ; \sqrt{2} 45∘;1245^\circ; \frac{1}{\sqrt{2}} 30∘;1230^\circ; \frac{1}{\sqrt{2}}

Multiple Choice Options

  • A 45o;2{45^o};\sqrt 2 4 5 o ; 2 _
  • B 30o;12{30^o};{1 \over {\sqrt 2 }} 3 0 o ; 2 _ 1 _
  • C 45o;12{45^o};{1 \over {\sqrt 2 }} 4 5 o ; 2 _ 1 _
  • D 30o;2{30^o};\sqrt 2 3 0 o ; 2 _

Step-by-Step Verified Solution

i = _ m + A 2 _ 45 o = _ m + 60 _ 2 _ _ m = 30 _ sin45� = _ sin30� _ 1 2 = _ 2 _ _ = 2
