Alrighty.
00:03
So in this scenario, we have a ray of light traveling through water, and then it's going to enter a diamond.
00:10
And so we want to know what the ray's angle of incidence is within the water.
00:25
And so when we draw out our diagram here, let's draw an x and y axis.
00:32
Okay.
00:32
So let's say that this side here, the water so this is water water and then you have our diamond over here diamond okay and we're going to have a ray light that is going this way and then it's going to hit the diamond and once it's within the diamond it's going to bend and relative to the y -axis it's going to be a 30 degree angle like so and what we want to to find is this initial angle of incidence data 1 within the water.
01:27
So the principle here is we're going to use our trusty relationship.
01:33
So we know that n1, so n1 and we have n2 down here.
01:40
These are the, these are fixed values that describe sort of the refractive properties.
01:48
Of different materials.
01:51
And so for example, water is always going to bend array of light a certain way and diamond depending on the internal composition of the material...
