Passage / Comprehension

For a glass prism the plot of deviation $(δ)$ vs angle of incidence (i) is as shown. If the refractive index of the glass is $μ$ and value of angle is $i_{1}$ . Then :\\

Find the value of $i_{1}$ (in degree) :

Answer:

41.00

Solution:

$δ = i + e - A$ and $δ_{min} = 2 i - A$

From the graph: $6 0^{\circ} = 12 0^{\circ} - A$ gives $A = 6 0^{\circ}$ ; then $63 = i_{1} + 2 i_{1} - 60$ gives $i_{1} = 4 1^{\circ}$
