Problem
For refraction through a small-angled prism, the angle of minimum deviation
(1) increases with an increase in the refractive index of the prism
(2) will be 2δ for a ray in a medium of refractive index 2.4 if it is δ for a ray in a medium of refractive index 1.2
(3) is directly proportional to the angle of the prism
(4) will decrease with an increase in the refractive index of the prism
