triboluminescence

what type if light is the production of light in living organisms

bioluminescence

what type of light is the production of light frim electruc current flowing through semiconductors; these are very energy efficient

incandescence

what type of light production of light from electricity flowing over a thin filament producing light and wasteful heat energy

led

what type of light is the production of light from the immediate emission kf visible light as a result of the absorption of ultraviolet light

flurescence

what type of light is the production of light from a pure, intense narrow beam

lazers

what type of light is the production of light from electric current passing through a gas, causing the gas to glow

electric discharge

what does the law of reflection state

1. the angle of incidence is equal to the angle of reflection
2.the incidence ray, reflected ray and normal all lie on the same plane

what are the two angles involved in reflection

1. angle of incudence
2. angle of reflection

what is specular reflection

reflection of light off a smooth shiny surface. rays reflect parrallel

what is diffuse reflection

reflection of light off irregular or dull surface. causes the light rays to bounce off in all directions

what are the types of heat energy

conduction, convection, or radiation

what happens to light when it hits different surfaces?

reflection, absorption or transmission

what are the wavelengths of light

Radio, microwaves, infrared, visible, ultraviolet, X-rays, gamma rays

what contols the amount of light entering the eye

iris

what bends light so it wnds up on the retina
