Here we look at basically reflection, right? so let me copy a diagram from the question.
00:11
So the diagram is this.
00:15
It's a very simple diagram, actually.
00:18
So here's the diagram, right? so here's diagram.
00:22
So basically you have an instant light going like this, and it's reflected, right? and this is a white light.
00:27
It has many different colors, but the refractive light has a single color, right? so one of this, this is obviously the, violet light and this is usually the red light, right? this is red and this is violet.
00:41
Because violet is more reflected than red light, right? as you know, then you'll ask about the reflected angle, right? the reflected angle is, you know, determined by snan's law, right? you know, for red light, the reflective index, and i mean, is 1 .59, but for valid, and we equals 1 .65, right? the refractive index, let me call it theta r and ceta v...
