|The production of light as a result of high temperature
|The process of producing light passing through an electric current
|The production of light by the absorption of ultra violet light resulting in the emission of visible light over an extended period of time
|The immediate emission of visible light as a result of the absorption of ultra violet light
|The direct production of light as the result of a chemical reaction with little or no heat produced.
|The production of light in living organisms as the result of a chemical reation with little to no heat produced
|The production of light from friction as a result of scratching crushing or rubbing certain crystals
|(light emitting diode) Light produced as a result of an electric flowing in semiconductors
|Example of how incandescence is used?
|Light bulbs. Not as efficient as florescence light bulbs.
|Example of how electric discharge is used?
|Example of phosphorescence?
|Glow in the dark stickers
|Example of florescence?
|Laundry detergent. Light bulbs. More efficient than incandescence.
|Example of chemiluminescence?
|Glow stick called cold light.
|Electromagnetic waves that the human eye can detect
|the classification of electromagnetic waves by energy
|Am/Fm radio, Tv signals, cell phone communication
|microwave ovens and astronomy
|remote controls, lasers
|human vision, theater lighting, rainbows
|medical imaging. cancer treatment, security equipment
|Cancer treatment, astronomy, product of some nuclear decay
|Continuous sequence of colours that make up white light (ROYGBIV)
|Where are the angles of incidence and reflection measured from?
|If reflected off a smooth surface inc. rays will?
|Inc rays will have a parallel reflection. Called specular reflection
|If reflected off a ruff surface the reflected ray will?
|Go in many different directions
|How are real images formed?
|By the convergence of light rays meeting at a point
|What do virtual images depend on?
|What do the observers see when they look into the mirror?
|The reflected rays
|How is the image formed?
|Where the observer thinks the rays are coming from
|What are the characteristics of images?
|Size, Altitude, Location and Type compared to object
|How many wave lengths does single colour light have?
|Is single colour light in phase?
|Does single colour light spread out?
|What is single colour light called?
|Where can laser lights be used?
|Medicine, military, industry and scientific research
|What is white light made out of?
|A mixture of colours
|Is white light made out of one wavelength?
|Does white light spread out?
|Is white light in phase?
|Is energy stronger in phase or out of phase?
|is white light concentrated energy?
|Why were lasers made?
|For scientific reasonsing
|What happens when light strikes matter?
|Can be absorbed transmitted or reflected
|Light that is soaked in by the matter it strikes
|Is it easier for black or white objects to absorb light?
|Bounces off the substance it strikes (mirror)
|Passes through the matter it strikes (transparent substances)
|Can see through clearly (window)
|Can see through but not with detail (frosted glass)
|Cannot see through at all (textbook)
