Edexcel Light and the EM Spectrum

The electromagnetic spectrum is a range of transverse waves that are transferred by the oscillations in electric and magnetic fields - hence the name.

Choose your topic:

Refraction - Waves that change direction when they meet a boundary

Colour [FREE] - How filters work and how we see colour from reflected light

Lenses - These refract light and can form an image of an object

Ray Diagrams - Convex and concave lenses and drawing the images they make

Images - Real and virtual images and how we can calculate their magnification

The Electromagnetic Spectrum - A range of transverse waves with many uses

Radios - How they work

Black Bodies - These are perfect emitters and absorbers of radiation

Radiation and the Earth - Climate change is happening and this is why
