Success Criteria:
I understand how a prism disperses white light into its component colours.
I am able to demonstrate how to use polarising filters to manipulate and analyse polarised light.
Fun Fact
Dispersion is responsible for the beautiful colours in soap bubbles! When light hits a soap bubble, the thin film of soap acts like a prism. The different colours we see are a result of the dispersion of light, where different wavelengths are refracted by different amounts.
Key terms
Dispersion of white light is the separation of its component colours when passing through a medium, such as a prism, due to varying refraction angles based on different wavelengths.
Polarisation of light is the orientation alignment of light waves in a specific direction, typically achieved by filtering out waves oscillating in certain planes perpendicular to the direction of propagation, resulting in light with a preferred polarization direction.
