Answer to Question #95470 in Optics for Kikelomo

Question

When color A and color B are sent through a prism, color A is bent more than color B. which color travels more rapidly in the prism? Explain.

Answer 1

Absolute refractive index is given by formula

$n=\frac{c}{v}(1)$

where c is the speed of light in vacuum

In our case, we have

$n_A > n_B (2)$

Using (1) and (2) we get

$v_B > v_A$

Answer

color B
