Reflection - Angle of incidence = Angle of reflection, Refraction - Change in speed and direction of light as it passes into a different medium, Medium - Substance a wave travels through, Angle of incidence - Angle light ray coming into medium makes with normal, Reference line drawn at 90 degrees to surface - Normal Line, Sin(90) - 1, Sin(0) - 0, Sin(45) - 0.71, Refractive index - Measure of how much light is slowed in a medium, Away from the normal - When light speeds up it will refract in this direction, Towards the normal - When light slows down it will refract in this direction, Straight on - When light is incident along the normal line it will go in this direction, Refractive index when angle of incidence is 30 degrees and angle of refraction is 20 degrees - 1.462, Refractive index when angle of incidence is 50 degrees and angle of refraction is 35 degrees - 1.336, Transverse - Light is this type of wave, Vacuum - Light can travel through a , Electromagnetic fields - Light travels via,
