We’ll cover the standard topics such as how we see things, pinhole camera, reflection (specular and diffuse), refraction, lenses, images. We’ll also consider ways to enhance these topics by;
• converting the pinhole camera to a lens camera,
• setting up a Pepper’s ghost demonstration,
• the role of refractive index in seeing things and how some objects can be made ‘invisible’.
• Practical activities to produce and locate images and to improve understanding of image formation.
• Using string diagrams.
Considering them as a continuous spectrum, with emphasis on;
• links to what students already know (such as visible light spectrum, colour)
• properties which are common to all.
• similarities between waves in adjacent sections of the spectrum.
• practical activities to enhance this topic which can sometimes be delivered in a rather dry and theoretical manner.
