What objectives does this worksheet meet?
Core
- I can define and use the terms normal, angle of incidence and angle of reflection.
- I can state that, in reflection, the angle of incidence is equal to the angle of reflection, and I can recall and use this relationship.
- I can define and use the terms normal, angle of incidence and angle of refraction.
- I can describe how light passes through a transparent material (only at the boundaries between two mediums).
- I can state what is meant by the critical angle.
- I can describe internal reflection and total internal reflection, using both experimental and everyday examples.
- I can draw and use ray diagrams to show how a converging lens forms a real image.
- I can describe the characteristics of an image using the terms enlarged/same size/diminished, upright/inverted and real/virtual.
- I can describe the dispersion of light, as shown when a glass prism refracts white light.
- I know the traditional seven colours of the visible spectrum, in order of frequency and in order of wavelength.
Extended
- I can recall and use the equation n = sin i / sin r.
- I can recall and use the equation n = 1 / sin c.
- I can describe how optical fibres are used, especially in telecommunications.
- I can draw and use ray diagrams to show how a converging lens forms a virtual image.
- I can describe how converging lenses and diverging lenses are used to correct long-sightedness and short-sightedness.
