In an experiment for determination of refractive index of glass of a prism by , plot, it was found that a ray incident at angle 350, suffers a deviation of 400 and that it emerges at angle 790⋅ Ιn that case which of the following is closest to the maximum possible value of the refractive index ?
Option: 1 1.5
Option: 2 1.6
Option: 3 1.7
Option: 4 1.8
Answers (1)
This angle is greater than the 40° deviation angle already given, For greater μ, deviation will be even higher. Hence, μ of the given prism should be lesser than 1.5. Hence, the closest option will be 1.5.
