SCI FINALS LENS Flashcards
1
Q
- is any transparent object with two nonparallel curved surfaces, or one plane surface and on curved surface.
A
LENS
2
Q
- farsighted
- are thicker in the middle than edges.
- considered as converging lenses because incidents rays that travel parallel to the principal axis of the lens are refracted and converge at F after passing through the lens.
A
convex lens
3
Q
- nearsighted
- are thinner in the middle and thicker at the edges.
- considered as diverging lenses because incident rays that travel parallel to the principal axis of the lens are refracted after passing through the lens, and then diverge so that they seem to originate at F
A
CONCAVE LENS
4
Q
- bending of light rays
A
REFRACTION
5
Q
- or double convex, or just convex
- if both surfaces are convex
A
BICONVEX
6
Q
if both surfaces have the same radius of curvature
A
EQUICONVEX
7
Q
- a lens with two cancave surfaces
A
BICONCAVE
8
Q
- if one of the surfaces is flat
- depending on the curvature of the other surface
A
PLANO CONCAVE / CONVEX
9
Q
- has a steeper concave surface and is thinner in the middle than at the peripheral parts
A
NEGATIVE MENISCUS LENS
10
Q
- has a steeper convex surface and is thicker in the middle than at the peripheral parts.
A
POSITIVE MENISCUS LENS
