| A | B |
| Newton | argued that light was of a particle nature |
| Young | first to prove experimentally the wave nature of light |
| Maxwell | proved mathematically that the visible colors are different frequencies of electromagnetic radiation |
| Newton | used a prism to separate sunlight into the spectrum of visible light |
| Ritter | discovered UV rays |
| Herschel | discovered IR or heat rays |
| diffraction | the spreading out of waves around the edge of a barrier |
| 700 nm | wavelength of red light |
| 400 nm | wavelength of violet light |
| refraction | the bending of light as it exits one media and enters into another |
| dispersion | the separation of white light |
| index of refraction | a measure of a media's optical density |
| law of reflection | the angle of incidence is equal to the angle of reflection |
| Snell's Law | links incident and refractive angles to their corresponding indices of refraction and the sine function |
| normal | a math term describing a line perpendicular to a surface |
| ROY G BIV | the colors of the visible light spectrum |
