| -recall and
label the different structures of the eye |
Link |
| -recall the
function of the iris, fovea, retina,optic nerve, aqueous and vitreous
humours, lens and cornea |
Link |
| -recall the
two types of nerve cells, rods and cones in the retina and explain
their function. |
Link |
| -explain how
vision can be impaired when light is poorly focused by the lens and
explain how glasses correct some simple defects. This can be done
using "Light Boxes". |
Link |
| -explain how
a convex lens refracts light by drawing simple ray diagrams |
Link |
| -explain how
a concave lens refracts light by drawing simple ray diagrams |
Link |
| -recall the
difference between a real and virtual image. |
Link |
| -trace and
describe the image formed by a convex lens of a distant object, an
object at 2 focal lengths away, an object at the focal length and
one within the focal length. Desribe the image using words such as
magnified, diminished, inverted, same size, upright, virtual or real. |
Link |
| -trace and
describe the image formed by a concave lens of a distant object as
it approaches the lens. Desribe the image using words such as magnified,
diminished, inverted, same size, upright, virtual or real. |
Link |
| -using ray
diagrams explain why a distant object, viewed through a magnifying
glass, appears smaller and inverted and why an object close to the
magnifying glass appears magnified and upright. |
Link |
| -explain how
a combination of lenses can magnify a distant object and act as a
telescope. |
Link |
| -recall that
plane mirrors produce virtual images that appear the same distance
into the mirror as the object is from the mirror. |
Link
|
| -recall that
the angle of incidence equals the angle of reflection and use this
rule to view objects with a plane mirror. |
Link |
| -describe
using diagrams how concave and convex mirrors reflect light. |
Link |
| -describe
the image formed by a concave mirror when the object is at a distance
of 4 focal lengths, 2 focal lengths, at the focal length and half
a focal length from the mirror. Use the words virtual, real, upright,
inverted magnified, same size. |
Link |
| -describe
the image formed by a concave mirror as the object approaches the
mirror. Use the words virtual, real, upright, inverted magnified,
same size. |
Link |
| -describe
how some illusions are created using concave or convex mirrors or
a combination of both. |

| -describe
how a kaleidoscope works using two flat mirrors. |
