So in this problem we're told that a blue ray of light has a higher index of a fraction than a red ray of light.
00:09
So what this tells us is that a blue ray of light is going to diffract more through a lens than the red ray of light.
00:18
So if we draw out what this means in the context of a diverging lens, we can go ahead and draw these red rays coming in parallel to this diverging lens initially.
00:32
And because this is a diverging lens, it's going to do as the name suggests.
00:36
And when it refracts, we're going to have these rays of light kind of coming out.
00:43
They're not converging.
00:44
They're diverging.
00:46
And we can do the same for the blue rays of light.
00:49
So assuming they're coming in sort of at the same, we have the same parallel rays of light coming in initially.
00:56
And because we have an higher index of a fraction for the blue ray of light, is we're going to refract more than the red light...
