| Photons | Packets of electromagnetic energy |
| Photoelectric Effect | the emission of electrons from a metal cause by light striking the metal |
| electromagnetic radiation | The transfer of energy by electromagnetic waves traveling through matter or across space |
| Magnetic Field | a region of space produce magnetic forces |
| Intensity | The rate at which a waves' energy flows through a given unit of area |
| Incandescent | the light produced when an object gets hot enough to glow |
| Fluorescence | a material that absorbs light a one wavelength and then emits light at a longer wavelength |

| Laser | a device that generate a beam of coherent light |
| Coherent Light | Light that has to have the same wavelength and the crest and troughs are lined up |
| Polarized Light | Light with Waves that vibrate only in one plane |
| Scattering | light is redirected as it passes through a medium |
| Dispersion | The process in which white light separates into colors |
| Primary colors | Three specifi colors that can be combined in varying amounts to create all possible colors |
| Secondary colors | a light combo of two primary colors |
| Complementary Colors of Light | Any two colors of light that combine to form white light |
| Pigment | a material that absorbs some colors of light and reflects other colors. |
| Complementary colors of pigments | Any two colors of pigments that combine to make black pigment. |
| Luminous | Objects that give off their own light |
| Electromagnetic Spectrum | The Full range of frequencies of electromagnetic radiation |
| Amplitude modulation | the amplitude of the wave is varied |
| Frequency Modulation | the frequency of a wave is varied |
| Thermograms | color coded pictures that show variations of temperature. |
| Transparent | a material that transmit light allowing most of the light to pass through it |
| Translucent | A material that scatters light |
| Opaque | either absorbs or reflects all of the light that strikes it |
| Image | a copy of an object formed by reflected or refracted waves of light |
| regular reflection | when parallel light waves strike a surface and reflect all in the same direction |
| Diffuse Reaction | occurs when paraleel light waves hit a rough uneven surface reflecting in multiple different directions |
| Mirage | a false or distorted image |
