The figure above shows a plot of angles of deviation through a glass prism when light is incident at θ degrees on the prism. The incident angle that produces the minimum deviation is

20^o

18^o

35^o

25^o

Explanation

From the given graph, when the angle of minimum deviation = 18º, the angle of incidence = 25º
