|
Opaque
|
Material that absorbs ot reflects all light that strikes it ex: wood, metal
|
|
Transparent
|
Material that transmits light ex: glass, air
|
|
Translucent
|
Material that allows only some light to pass - scatters light ex: wax paper, fogged glass
|
|
Regular Reflection
|
Parallell rays of light hit a smooth surface
|
|
Diffuse Reflection
|
Parallel rays of light hit a bumpy or uneven surface
|
|
Image
|
Copy of an object formed by reflected ot refracted rays of light
|
|
Plane Mirror
|
One that is flat; produces an image that is right side up and is the sam size as the object being reflected; virtual image
|
|
Virtual Image
|
Images that are right-side up or upright
|
|
Concave Mirror
|
Curves inward liek a bowl; reflects parallel rays of light so they meet at a point; forms virtual or real images
|
|
Real Image
|
Upside down, or inverted, the object is between the focal point and mirror. Image appears to be behind the morror and right-side up - virtual image
|
|
Convex Mirror
|
Surface curves outward. since rays do not meet, the image formed by a convex are always virtual. They appear smaller and farther away than they are
|
|
Index of Refraction
|
Measure of how much a ray of light bends when it enters the material.
|
|
Lens
|
Curved peice of glass or other transparent material used to refract light
|
|
Concave Lens
|
Thinner in the middle than at the edges. spreads out parallel rays of light. can only produce a virtual image.
|
|
Convex Lens
|
Thicker in the center than at the edges; Acts like a concave mirror because ot forms rays of light
|
