For the angle of minimum deviation of a prism to be equal to its refra...
The angle of minimum deviation is given as
δmin = i + e–A
for minimum deviation
δmin = A then
2A = i + e
in case of δmin i = e
2A = 2i r1 = r2 = A/2
i = A = 90°
from smell’s law
1 sin i = n sin r1
sin A = n sin A/2
when A = 90° = imin
then nmin = √2
i = A = 0 nmax = 2

1 and 2
b)is greater than 2
c)is less than 1
d)is equal to 1
d) is equal to 1.
When the angle of minimum deviation is equal to the refracting angle, the prism is said to be in minimum deviation position. In this position, the angle of incidence and angle of emergence are equal, and the angle of deviation is minimized. This condition is achieved when the refractive index of the prism material is equal to the refractive index of the medium outside the prism (usually air), which is 1.

c)is less than 1
d)is equal to 1
