mirrors and lensesq

divergent lenses

concave

convergent lenses

convex

real image

formed by the converging of reflected light waves

virtual image

reflected light ways do not properly converge, but mirror structure reconstructs light into image based on where it came from

concave mirror focal point

located on same side as the object

convex mirror

located on the opposite side of the object

determining focal point

divide lense radius by 2

thin lens equation

positive image value indicates

the image is realn

egative image value indicates image is

virtual

positive focal point indicates

lens is convex

negative focal point indicates

lens is concave

magnefication

-(1/object distance)

negative magnification value

image is inverted and real

positive magnification value

image is upright and virtual

power

1/focal point

power units

diopters

positive power interpretation

coverging/convex lense

negative power interpretation

diverging/concave lense

spherical abberation

light that hits closer tp center of a spherical lens focuses farther away than a lens that hits closer to the edge, causing multiple focal points
