Question

In the diagram, a plot between δ (deviation) versus i (angle of incidence) for a triangular prism is given. From the observed plot, some conclusions can be drawn. Mark out the correct conclusions

(a) The range of deviation for which two angles of incidence are possible for same deviation is δ₀ - δ_m 

(b) The curve is unsymmetrical about i_o

(c) For a given δ, i is unique

(d) Both (a) and (b) are correct

Answer 1

Correct Option (d) Both (a) and (b) are correct

Explanation:

The range of deviation for which two angles of incident are possible for same deviation is δ₀ - δ_m  and the given curve is symmetrical about i_o
