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 the angles of minimum deviation for red and blue light,respectively,in a prism of this glass. Then,

  • A
    $D_1 > D_2$
  • B
    $D_1 < D_2$
  • C
    $D_1 = D_2$
  • D
    The relationship between $D_1$ and $D_2$ depends on the prism angle of the prism.
