P Flagquestion

White light is incident on a block of glass that has index of refraction $n=1\mathrm{.}816$ for violet light and $n=1\mathrm{.}800$ for red light. The thickness of the block is $L=27cm.$ If the angle of incidence is $43$ degrees, what is the distance $x$ between the violet and red rays when they emerge from the glass? Take the index of refraction of air to be $1\mathrm{.}00.$
