You're given a diagram and you're asked to find the location of the image using ray tracings.
00:08
So you have a diagram with something like this.
00:11
One of the rays is going to travel from the tip of the object, which is the arrow i have indicated on the left, through the focal point to the center of the lens, something like this.
00:26
And that ray will come out parallel to the principal axis.
00:35
So something like this.
00:40
And then a second ray is one that comes parallel to the principal axis from the object.
00:51
And that one will refract through the far focal point.
00:59
So something like this.
01:03
So that intersection would indicate the tip of the image of that arrow.
01:07
So you notice it's going to be inverted...
