A beam of monochromatic light is incident on one face of an equilateral prism, the angle of incidence being 550. If the angle of emergence is 460then the angle of minimum deviation is –
A
410
B
< 410
C
> 410
D
³ 410
Answer
< 410
Explanation
Solution
A = 600; i = 550; e = 460
\ i + e = A + d
550+ 460= 600 + d
Ž d = 410 dmin < d
