JEE Mains · Physics · STD 12 - 9. Ray optics and optical instruments
In an experiment for determination of refractive index of glass of a prism by \(i - \delta\) , plot it was found thata ray incident at angle \(35 ^o \), suffers a deviation of \(40 ^o \) and that it emerges at angle \(7 9 ^o \). In that case which of the following is closest to the maximum possible value of the refractive index?
- A \(1.7\)
- B \(1.8\)
- C \(1.5\)
- D \(1.6\)
Answer & Solution
Correct Answer
(C) \(1.5\)
Step-by-step Solution
Detailed explanation
We know that \(i+e-A=\delta\) \(35^o+79^o-\mathrm{A}=40^o\) \(\therefore \quad \mathrm{A}=74^o\) But \(\mu = \frac{{\sin \left( {\frac{{{\text{A}} + {\delta _{\text{m}}}}}{2}} \right)}}{{\sin {\text{A}}/2}}\)…
