Geometric optics: graphical solutions to curved mirrors problems

Problem analysing, develop creativity, critical thinking and problem solving in optical geometry.
The major advantage of graphical approach to the conventional method of solving optical geometry problem is that it helps students to create a scenery of the object-image formation, rather than cramming various imagery formations and positions.
Once students can remember the principles if drawing ray diagrams in optical devices, the can use graph to analyse the image position without having to cram them.
