1.the diffuse(partially reflected ray) does not really suffice/add impetus but actually brings some confusion as to whether, say glass, water, etc reflects or refracts light rays.

  1. there is need for arrows (or arrowheads) to clearly show the directions of the rays of the laser lights. We put so much emphasis on this when we teach and assess.
  2. The concept of critical angle is nearly impossible to address/explain given that the laser light ray does not ever go along the boundary/interface of the 2 different optical media so as to make the angle of refraction equal to 90 degrees, which is so important to put across with the aid of simulations.
  3. Can the laser light projector be made to rotate through 180 degrees vertically so that we do not have to change the optical media in order to teach/explain/demonstrate Total Internal Reflection.
