We developed teaching materials such as Slide Projectors, Solar Cells and Polarized Plats to understand that light travels in a transverse wave and brightness proportional to the square of the amplitude of electromagnetic waves.Next, we developed the experiments to enable students to grasp Plank's law and Wien's Displacement Law.Then, we developed experiments using small electromagnets to observe Faraday Rotation and understand the interaction between electromagnetic waves and matter.
