Variation of angle of deviation $δ$ versus angle of incidence $i$ for a prism is given the figure. The value of refractive index of prism :-

Answer:

Solution:

$d = i + e - A$

$3 0^{\circ} = 9 0^{\circ} - A$

$A = 6 0^{\circ}$

$μ = \frac{s i n ( \frac{A + δ _{m}}{2} )}{s i n ( \frac{A}{2} )}$

$μ = \frac{s i n 4 5 ^{\circ}}{s i n 3 0 ^{\circ}} = 2$
