One way of finding the images that occur for an object for a converging and for diverging lens is ray tracing. There are three principle rays that we can use to find the image. The first one are parallel rays. They go through the focal point. So for the converging lens, this means a ray that is parallel will go through the focal point on the right. This is what is called the converging lens as it converges parallel rays on the right side. For the diverging lens, it was quite similar. However, the parallel ray is not going through the focal point on the left. So it is just virtually going through the focal point. There is no real light on the left side. I am drawing a dotted here. Then it goes like this. So here the light is diverging. Parallel light is spreading out in different directions. Now here the parallel rays converge. They come to that. Now the second type of ray that we can look at is kind of the inverse of the one that we just did. Any ray through the focal point will become parallel. So on the left side for the converging lens, we are using the left focal point. And this ray will become parallel. For the diverging lens, we do the same thing as before. We use the other focal point as the one used for the converging. So here we use the left one. That means here we are using the right focal point. So a ray that is aimed at the right focal point like this will become parallel. And then backtracking it where we think it comes from when we look through the lens from this side. Then there is a last ray that we can use. That is one that goes through the center. It just goes straight through. Actually only two rays to find damage. But if you have a third one that can confirm the location of the image. So that is actually easiest. One that goes through the center of the lens does not change direction at all. So one that goes through the center of the lens. Here is the center. It does not change direction at all. So it can here. One that goes through the center of the lens. It does not change direction at all. Now in both cases which is found the image. The image is where all the rays meet again. So here in the case of the converging lens. If we were an object that was placed behind the focal point. I got the real image real because the rays really meet here. And it's outside that. In case of the diverging lens. We have to make three rays appear to meet. They appear to meet here. I am looking from this side. I am seeing them coming out from this point. So what I see is an image. Here behind the lens. So it is a virtual image. But the light does not really come from there. These two rays just appear to be coming from this direction. So for the diverging lens. We have an object on the next side of the focal point. I got a virtual image here.
