Colours, Waves and Particles
Every time you’re seeing an object, it’s all thanks to light. This video explains electromagnetic radiation, the visible light spectrum and how light travels as waves but behaves as particles, through engaging visuals and informative diagrams.
Refraction, Lenses and Polarisation
When light travels from one medium into another, its speed changes – that’s refraction! This video demonstrates refractions and explains how lenses work and how polarisation filters light, through engaging visuals and informative diagrams.
Reflection and Mirrors
Objects can only be seen because they reflect light. This video explains how objects absorb and reflect different wavelengths, how mirrors work, and why the shape of a surface impacts reflection, through engaging visuals and informative diagrams.
