Two prisms one made of crown glass ( 
= 1.58, 
= 1.52) and second made of flint glass ( 
= 1.48, 
= 1.42) are arranged as shown. Angle of prism for crown glass prism is given 9°. Now choose the incorrect statements :

CHECK THE SOLUTION.
(c, d)
] For zero deviation. A 1 ( 
– 1) = A 2 ( 
– 1)
9 (1.55 – 1) = A 2 (1. 45 – 1)
9 × 0.55 = A 2 × 0.45
A 2 = 11 0 For zero dispersión.
A 1 ( 
– 
) = A 2 ( 
– 
)
9 (0.06) = A 2 (0.06)
A 2 = 9 0
