Light waves

Light is conceptually difficult for many students and misconceptions can persist unless challenged.  The resources in this list not only provide a range of activities and demonstrations, but also background information, practical tips, information on misconceptions and suggested teaching strategies.

This list links to the following topis;

• light waves travelling through a vacuum; speed of light
• the transmission of light through materials: absorption, diffuse scattering and specular reflection at a surface
• use of ray model to explain imaging in mirrors, the pinhole camera, the refraction of light and action of convex lens in focusing (qualitative); the human eye
• colours and the different frequencies of light, white light and prisms (qualitative only); differential colour effects in absorption and diffuse reflection

Whilst this list provides a source of information and ideas for experimental work, it is important to note that recommendations can date very quickly. Do NOT follow suggestions which conflict with current advice from CLEAPSS, SSERC or recent safety guides. eLibrary users are responsible for ensuring that any activity, including practical work, which they carry out is consistent with current regulations related to Health and Safety and that they carry an appropriate risk assessment. Further information is provided in our Health and Safety guidance.
