Thin lenses

what is the power of a thin lens determined by

the sum of the power of the two surfaces

equation for thin lens power

F=F1+F2

what can you deduce mathematically about thin lenses

the image position

what are the same in thin lenses

n and n'

what is the effect of n and n' being the same

F and F' have identical focal lengths

Define: Ray Tracing

graphical construction of an image

when are primary and secondary focal lengths the same

when n and n' are the same

what is the power of thin lenses in contact

add the powers together

what is the emergent light at F2, of lenses separated by distance called

back vertex power

if multiple lenses separated are brought together, what has to be changed

the power of a lens so the focus remains at F'

what does Fe stand for

equivalent power

how are objects and images through a lens system related

by newton's formula
