Description
🔍 Explore
Discover how light bends and reflects when crossing between different materials like air, water, and glass. Measure angles, test different light colors, and explore total internal reflection.
🎮 Try It
• Adjust the angle slider to shine the light beam at different angles against the boundary.
• Change the top and bottom materials to compare how light behaves moving from air into glass versus glass into air.
• Check Protractor and Intensity to measure the exact angles and the percentage of light that reflects or refracts.
🎯 Your Mission
Set the top material to Glass and the bottom material to Air, then find the exact angle where the refracted ray disappears.
🌍 Real-World Connection
Fiber optic cables transmit internet data across oceans by bouncing light inside glass strands using total internal reflection without letting light leak out.
