Trace principal rays and predict image position, size, and orientation.
This browser-based interactive simulation helps you trace principal rays and predict image position, size, and orientation. Designed for Grades 6–12, it turns an abstract idea into a model you can control, measure, reset, and test without signing up.
Explore Convex lens, concave lens, focal length, image distance by changing the available controls and comparing the model’s visual and numerical evidence. Try one variable at a time, then combine changes to test a stronger explanation.
A typical investigation takes 7–12 min. Use it as a lesson demonstration, a guided inquiry activity, a homework experiment, or a quick review. The simulation runs in a modern web browser and does not require an account.
Trace principal rays and predict image position, size, and orientation. The main ideas are Convex lens, concave lens, focal length, image distance.
Yes. You can run the simulation online for free without creating an account.
Most learners can complete one investigation in 7–12 min. You can repeat it to compare more variables or improve your explanation.
