Please have on Desk: EM bookletEM booklet

Visible Light Notes Sun (Natural Light) –Uses Heat to create EM Energy –INCANDESCENCE

Incandescent bulb –Uses electricity to create heat, which creates visible light Visible Light Notes Lamps; Overhead lights

Visible Light Notes Fluorescent bulb –Gas inside of bulb responds to electricity by creating U.V. Light; Special coating absorbs U.V. Light and give off visible light. –More energy efficient than incandescent. Lamps; Overhead lights

Visible Light Notes Halogen Bulbs –Uses electricity to create heat which produces visible light (A form of Incandescent light). – More heat than incandescent bulb, but filament lasts longer. Overhead projectors; Car headlights; large spotlights

Visible Light Notes Neon Bulbs. – Gas inside of tube (like neon or argon) responds to electricity by creating visible light –Type of gas determines color of light. Art; signs

Visible Light Notes LED Bulbs –Uses electricity to produces light (NO HEAT CREATED) – Light is less intense than other forms, so multiple bulbs are often used. Christmas lights; Stop Lights

Visible Light Notes Bioluminescent –Uses chemicals reactions inside animals to produce light To see, mate or warn/hunt
