The refractive index of glass is

\mathrm{1}\mathrm{.520}

for red light and

\mathrm{1}\mathrm{.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 ,

View answer and explanation

Correct option: A

{D_1} < \,\,{D_2}

Option A (

{D_1} < \,\,{D_2}

) is correct because the angle of minimum deviation is directly proportional to the refractive index, and blue light has a higher refractive index than red light.
