Reflection and Refraction
by Anonymous
Move an object toward and away from a mirror, water surface, and convex lens to trace the rays and see where each image forms and how big it looks.

About this app
Reflection and Refraction is an interactive middle school physics app about how mirrors, water, and convex lenses form images. Explore plane-mirror images, apparent depth in water and glass, and the different image types produced by changing an object's distance from a convex lens. Each section uses selectable values, illustrated ray diagrams, step-by-step challenges, and immediate feedback.
Use cases
- Middle school students studying light and optics
- Teachers demonstrating reflection and refraction concepts
- Learners practicing image formation with guided challenges
- Parents exploring introductory physics with children
Features
- Interactive mirror simulation with four object distances and four heights
- Shows equal mirror-image distance and height, object-image separation, and left-right reversal
- Compares apparent depth in water and glass using selectable real depths
- Convex-lens simulation showing upright, inverted, magnified, reduced, equal, or absent images
- Guided missions with reset, next, progress, and instant feedback controls
