PhysicsEasysingle choice

The refractive index of 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,

Options:

Answer:

Solution:

$D = (μ - 1) A$ For blue light $μ$ is greater than that for red light, so $D_{2} > D_{1}$ .
