Ray Tracing Dad Hat

The ray tracing dad hat  shows the three rays used to show the image formation by a convex lens.

The ray leaving the object parallel to the principal axis is sent through the focal point on the other side of the lens.

The ray leaving the object and travelling through the center of the lens has a very small offset as it travels through the lens.

The ray leaving the object and passing through the focal point on the same side of the lens and comes out parallel to the principal axis on the other side.

The place where these three rays meet up is where the image is formed on the other side of the lens.

In reality, each point on the lens facing side of the object sends light towards and through the lens.  We just use these three rays to determine the top of the image.
