Big Idea: Waves carry information without causing a permanent change on the intervening medium. More info...
Class practical: Placing the final image at reading distance from the eye, as an astronomer would.
Class practical: Comparing the curvature and shape of long and short focus lenses.
Class practical: Producing a permanent photographic image.
Class practical: Constructing a pinhole camera and investigating the action of a lens.
Class practical: The caustic curve and how the aberration can be reduced by reducing the aperture.
Class practical: Showing angle of incidence equal to angle of reflection.
Demonstration: This experiment is well worth the effort of setting it up.
Demonstration: Comparing the paths of a reflected ray of light and a rubber ball.
Class practical: Shows that image and object positions are symmetrical in a plane mirror.
Class practical: identifying that the image in a plane mirror is virtual.
Demonstration: Three simple demonstrations of the refraction of light at an air-water interface.
Demonstration: Refraction at an air-water interface and total internal reflection.
