Cards Term photon Definition a particle of light Term polaring lenses Definition lenses which are made naturally that allows light waves vibrating in only one direction to pass through Term photo electric effect Definition occurs when light shines on certain metals and produces an electric current Term incadecent light Definition produced when a thin filament made of tungsten glows when heated Term fluorescent light Definition provided when gases inside the glass tube gives off UV light causing the phosphorus coating to give off visible light Term illuminous Definition objects which produce and give off their own light Term transparent Definition allows light to pass through easily and objects can be seen clearly Term translucent Definition some light passes through the material, but ojbects can not be seen clearly Term opaque Definition allows no light to pass through an object Term addictive primary colors Definition red, blue green (color of light that when mixed together roduce white light) Term subtractive primary colors Definition yellow, cyan and magenta (colors of filter or pigments that when combined produce red or green Term light ray Definition a model of light that represents light travelling through space in an imaginary straight line Term diffuse reflection Definition reflections of light at all angles and in random directions caused by a rough surface Term law of reflection Definition the angle of incidence equals the angle of reflection Term flat mirrors Definition forms images using the law of reflection Term virtual Definition an image that forms at a point from when light rays appear to come but do not actually come Term concave mirror Definition is intended (curves inward) Term a real image Definition an image formed by many light rays coming together in a specific location...a real image is always inverted Term convex mirror Definition a mirror that bulges outward Term refraction Definition the bending of light waves as they pass from one medium into another Term prism Definition a transparent block with a triangular cross section Term mirage Definition a virtual image caused by the refraction of light in the atmosphere Term lense Definition transparent object that refracts light rays causing them to converge or diverge to create an image Term convex lense Definition a lense which is the middle that bends the light rays inward as they pass through Term magnification Definition a change in the size of an image compared to the size of the object Term concave lense Definition a lense which is thicker at the ends it bends the light rays outward as they pass through
