Plane mirror image details
|
Virtual, erect, same size as obj, just as far behind the mirror as the obj is in front of the mirror
|
|
Examples of plane mirrors
|
Mirror in bathroom & bedrrom
|
|
Virtual image
|
The light rays don't come from the image; the image seen is a copy of an obj formed at the location from which the light rays appear to come
|
|
Convex mirror image details
|
F is -ve; image is erect, virtual, smaller than obj, behind the mirror
|
|
Convex mirror ex
|
In-store mirrors that capture a large view of the store; it is a smaller image, but a larger field of view. use these mirrors to find mike at the store
|
|
Focal length (f)
|
Half the radius of curvature
|
|
Eqn for distance of images/objs
|
1/f = 1/do + 1/di
|
|
Eqn for size of obj/images
|
Si = so (di/do)
|
|
Concave mirror image details
|
F is +ve; image is real, inverted, & in front of lens or virtual, erect, & behind lens
|
|
Examples of concave mirrors
|
Magnifying glass; used to groom facial hair; image larger but smaller field of vision
|
|
Concave lenses
|
Follow the rules of convex mirrors; lenses are thinner in the middle than at the edges
|
|
Convex lenses
|
Follow the same rules as concave mirrors; lenses are thicker at the middle than at the edge
|
|
Combination of lenses
|
The lenses' power is measured in diopters and is the reciprocal of f (f should be in meters). When lenses combine, the powers add.
