When the angle of incidence increases the angle of deviation:
A. decreases to its minimum value
B. increases with increase in angle of incidence
C. first decreases to minimum value and then increases with increase in angle of incidence
D. decreases with increase in angle of incidence.
Answer:C
When the angle of incidence increases the angle of deviation:
A. decreases to its minimum value B. increases with increase in angle of incidence C. first decreases to minimum value and then increases with increase in angle of incidence D. decreases with increase in angle of incidence.
Explanation: The angle of deviation depends on the shape of the prism and the angle of prism.
