OPTICS - types of lenses, uses and ray diagrams all
explained and the correction of eye defects
Doc Brown's GCSE level Physics study revision notes
Sub-index for this section on optics - lenses (F =
focal length of a convex lens)
1.
Reminders of what happens when light
rays pass through different shaped prisms
2.
The types and properties of lenses, how to construct ray
diagrams, measurement of focal length F
3.
Convex lens ray diagram for a real image when object is a distance of 2F
from the lens
4.
Convex lens ray
diagram for a real image if object is a distance between F and 2F from
lens
5.
Convex lens ray diagram for virtual image when object is at a distance
between F and
lens
6.
Convex lens ray diagram for when object is at a distance
beyond 2F
7.
Ray diagram for a
concave lens showing the divergence of parallel rays
8.
Ray diagram showing
the formation of a virtual image by a concave lens
9.
Eye defects - explaining short sightedness and long sightedness -
correction using lenses
