Objective: Demonstrate and investigate the phenomena of interference, diffraction and polarisation using microwaves
Using microwaves, many experiments can be conducted on interference, diffraction and polarisation, as an aid to understanding these phenomena for visible light. Diffracting objects and polarisation gratings can be used which possess a structure that can be seen with the unaided eye and easily understood. In the case of diffraction by a pair of slits, maximum intensity can be detected at a position where radiation travelling in a straight line from the transmitter could not possibly reach.
