Term | Definition |
---|---|
Angle of incidence | The angle at which light hits a reflective surface |
Angle of reflection | The angle at which light leaves a reflective surface |
Diffraction | The apparent bending of waves around small obstacles and the spreading out of waves past small openings |
Electromagnetic radiation | energy that travels in waves across space as well as through matter |
Electromagnetic spectrum | the range of wavelengths or frequencies over which electromagnetic radiation extends |
Fiber optics | Optical fibers that can carry light over long distances that are used in communication and data transfer |
Frequency | the number of complete wavelengths that pass a point in a given time |
LASER | Light Amplification by Stimulated Emission of Radiation |
Lens | An optical device which transmits and refracts light, converging or diverging the beam |
Mirror | A substance that can reflect light efficiently |
Photon | A bundle of light energy that moves as both a particle and a wave |
Primary colors | Colors that can be added or subtracted from one another to create other colors. Red, Blue, Green, Cyan, Magenta and Yellow. |
Prism | A substance that can refract white light separating it into its colored components |
Reflection | The change in direction of a wave from the surface of a reflective material |
Refraction | The bending of a wave when it enters a medium where its speed changes due to differences in density |
Speed of light | The speed at which light travels in a vacuum. ( 3.00 x 108 m/s) |
Wave particle duality | The dual nature of light that explains the wave and particle characteristics that light exhibits |
Wavelength | the distance from any point on a wave to an identical point on the next wave |
