4.4 Waves
This topic provides knowledge and understanding of wave properties, electromagnetic waves, sound waves superposition and stationary waves. The wavelength of visible light is too small to be measured directly using a ruler. However, superposition experiments can be done in the laboratory to determine wavelength of visible light using a laser and a double slit.
There are opportunities to discuss how the double-slit experiment demonstrated the wave-like behaviour of light.
