Net Force (and Acceleration) Ranking Tasks, Trajectory - Horizontally Launched Projectiles, Which One Doesn't Belong? Object distance (p) and image distance (q) are automatically generated. Go to "Geometric Optics" and open the program. Use diagrams of the Projectile Motion. The image through the concave lens is always a virtual image, standing like an object, and looks smaller than the real thing. PhET Simulation: Geometric Optics - AAPT not a disease. Real image: Indicates that the light is actually gathered there and then starts again. BLOCKERS Optics to Run Now! Take some time to play with the simulation to get familiar with how it works. If you put the paper in the position where the actual image is formed, you can actually see the image formed on the paper.
Move the yellow arrow to a position that is halfway between f and the lens. They are also used in flashlights to magnify the light, and can be found in door viewers or peepholes. Oatccc State Indoor Championships,
