3.2 Light
- 3.2.1 Reflection of light
- describe the formation of an optical image by a
plane mirror, and give its characteristics
- recall that the image in a plane mirror is virtual
- recall that the image in a plane mirror is virtual
- perform simple constructions,
measurements and calculations for
reflection by plane mirrors
- recall and use the law
angle of incidence =
angle of reflection
- describe the formation of an optical image by a
plane mirror, and give its characteristics
- 3.2.2 Refraction of light
- describe an experimental
demonstration of the
refraction of light
- recall and use the definition
of refractive index n in terms
of speed
- recall and use the equation sin i / sin r = n
- use the terminology for
the angle of incidence i
and angle of refraction r
- describe the passage of light through
parallel-sided transparent material
- describe the passage of light through
parallel-sided transparent material
- recall and use n = 1/sin c
- give the meaning of critical angle
- describe internal
and total internal
reflection
- describe and explain the
action of optical fibres
particularly in medicine and
communications thechnology
- describe an experimental
demonstration of the
refraction of light
- 3.2.3 Thin converging lens
- describe the action
of a thin converging
lens on a beam of
light
- use the terms ..
- focal length
- principal focus
- focal length
- draw ray diagrams
for the formation
of a real image by a
single lens
- draw and use
ray diagrams for
the formation
of a virtual
image by a
single lens
- draw and use
ray diagrams for
the formation
of a virtual
image by a
single lens
- describe the nature of an
image using the terms ....
- enlarged/same size/diminished
- upright/inverted
- enlarged/same size/diminished
- use and describe the use of a single
lens as a magnifying glass
- show understanding of the terms
real image and virtual image
- describe the action
of a thin converging
lens on a beam of
light
- 3.2.4 Dispersion of light
- give a qualitative account of the dispersion of light as
shown by the action on light of a glass prism including
the seven colours of the spectrum in their correct order
- recall that light of a single frequency is
described as monochromatic
- give a qualitative account of the dispersion of light as
shown by the action on light of a glass prism including
the seven colours of the spectrum in their correct order
