SOURCES OF VISIBLE LIGHT
Incandescent Light
Light that is produced by an object such as metal, that is at a high temperature
-
-
Phosphorescent Light
Light sources that stores the energy from a source of light and emits it slowly over a long period of time
-
-
-
Electric Charge
Method of producing light in which an electric current passes through the air, or another gas
-
-
-
Plasma Display
Light source including tiny fluorescent lights in which an electrical signal causes a gas (such as neon) to release UV radiation
-
-
TYPES OF ENERGY
Chemical Potential Energy: a source which converts chemical energy stores within molecules into light energt
-
-
*Nuclear Potential Energy: a source which converts energy stored within the nucleus of atoms into light energy through fission or fusion
TYPES OF MIRRORS
Plane Mirror: any mirror that has a flat reflective surface 
Curved Mirror: mirrors that are outward-curved (convex mirrors) or inward curved (concave mirrors)
DESCRIBING IMAGES
Size: the image can be smaller, larger or the same as the object
-
Type: the type and location of an image are related. The type of image often depends on its location
-
Virtual Image: image can only be seen by looking at the optical device – the image is behind the mirror
Location: in front of the mirror or in the back of the mirror. (This can be use to determine the type
-
INDEX OF REFRACTION
-
the more optically dense the medium, the more it will slow down the speed of light and the large its refractive index is
