||
| Diffraction Grating Glasses | Inexpensive diffraction grating glasses are used to observe the spectra of many sources. | |

| Sulphur Dioxide | Cylindrical lens appears to invert the word SULPHUR but not DIOXIDE. | |
|
Notes | |||
| Water Stream Fibre Cable | Total internal reflection in a stream of water. | |
|
Video | |||
| Total Internal Reflection In a Prism | See the teacher through the prism. Related to binoculars, suitable for large lecture theatre with video camera. | |
|
Notes | |||
| White Board Optics | Five laser beams represent rays through various lens and mirror optics on board at front of classroom. | |
|
Notes | |||
| Large Converging Lens | Measure focal length f and get a large image with a large converging lens. For use in a large lecture theatre. | |
|
Notes | |||
| Covering Half of a Large Lens | Observe that covering half of the lens just makes the image dimmer rather than removing half of the image. | |
|
Notes | |||
| Simple Telescope | Two lenses, a metre stick, and bluetak are used to make a simple telescope that illustrates angular magnification. | |
|
Notes | |||
| Infrared Webcam | While the eye is not sensitive to infrared radiation, many web cameras and inexpensive video cameras can image infrared light that is near the edge of visible. | |
|
Notes | |||
| Thermal Camera | An infrared camera with thermal imaging capability produces images in the midwave infrared and can be used to measure temperatures. | |
|
Notes | |||
| Computer Colours |
Combining colours: A computer display or TV set makes only Red, Green, and Blue dots. RGB technology using these dots can be used to fool the eye into seeing other colours that are not actually present. | |

| Through the Looking Glass: RGB Technology |
RGB video displays produce red, green and blue light in a range of intensities to imitate a range of colours. Diffraction grating glasses break up the light from a video display to show the red, green and blue components. | |
