Strand 2: Wave Motion & Energy Transfer

Simulations

2.1  The transfer of heat energy and temperature change

• Conduction in a metal
• Convection in a liquid
• Convection in a gas
• Radiation from different surfaces
• Sand batteries as an energy
• Sand batteries explainer (YouTube video)
• How a refridgerator works
• Looking at the inside of a fridge

2.2 Travelling waves as models of disturbances transferring energy without transferring matter

 > Transverse and Longditudinal waves

2.3 Wave behaviour caused by the interaction of waves with their environment

• Reflection of light
• Refraction of light
• Ray diagrams for lenses (Phet simulation)
• Total internal reflection
• Optical fibres
• Converging and Diverging lenses

2.7 Wave effects
