Competitive Physics Optics
Optics Lab · all topics
Interactive Optics

Optics, drawn on the board.

Drag the object. Orbit the bench in 3D. Watch the rays converge exactly where the maths says they will.

principal axis
The sign convention start here — it runs through every module

All distances measured from the pole. Light travels left→right = positive. Get the signs right and every formula just works.

pole + direction · incident light → + x − x object
