22.5 Thin Lenses Real Image by a Converging Lens

Explanation: The video shows a single convergent lens with the object placed outside the focal point, so a real image is formed. The object used in this simulation is the letter T. The lens is represented by a blue circle with dots placed on either side to designate the focal point. The moving gray square simulates a viewing screen. As discussed in Section 22.5, a real inverted image is formed on the other side of the lens. The simulation ends when the position of the image is found.  You can determine this position either by using a Ray Diagram, as shown in Section 22.6 or by using Equation 22.5.
