$$ + 20\,cm$$

AIEEE 2006

MCQ (Single Correct Answer)

-1

The refractive index of a glass is $$1.520$$ for red light and $$1.525$$ for blue light. Let $${D_1}$$ and $${D_2}$$ be angles of minimum deviation for red and blue light respectively in a prism of this glass. Then,

$${D_1} < {D_2}$$

$${D_1} = {D_2}$$

$${D_1}$$ can be less than or greater than $${D_2}$$ depending upon the angle of prism

$${D_1} > {D_2}$$

$$-1$$ $$D$$

$$1$$ $$D$$

$$-25$$ $$D$$

$$25$$ $$D$$
