Angle of Incidence, Angle the light ray going in makes with the normal, Angle of reflection, Angle the light ray that bounces off the mirror makes with the normal, Transverse, Light Is this type of wave, Vacuum, Light can travel through this, Reflection, When light bounces off a surface in a predictable way, Refraction, When light enters a medium of different density, Medium, Something a wave travels through, Towards the normal, When light slows down it bends in this direction, Away from the normal, When light speeds up it bends in this direction, Normal line, Reference line at 90 degrees to the surface, Law of reflection, angle of incidence = angle of reflection, Protractor, Use to measure angles, Lens, Use to make the light beam from the ray box nice and narrow, Longitudinal, Sound is this type of wave, Electric and magnetic fields, Light travels via these, 300,000,000 m/s, Speed of light, v = f x w, Wave speed equation, Time period, Time for 1 complete wave cycle, Frequency, Number of wave cycles per second, Energy, Light transfers this, Matter, Light does not transfer this.
