AQA AS Physics Chapter 5 Optics LATEST UPDATE Normal Imaginary line perpendicular to the boundary between two materials or a surface. Partial reflection When some of the wave bounces off a surface, as it does when light moves from air to a refractive substance. Refractive index Ratio of sin i to sin r. Also the ratio of the speed of light in a vacuum to the speed of light in the material. Also the ratio of the wavelength of light in a vacuum to the wavelength of light in the material. 1...
