Physics Waves AQA AS Exam Questions and Answers 100% Pass What does a wave do? Transports energy from one place to another What are mechanical waves? Mechanical waves use particles to transfer energy (neighboring particles bump into each other and set their neighbors moving) What are electromagnetic waves? Electromagnetic waves don't use particle vibration to transfer their energy and can therefore travel through a vacuum. e.g. light What is the unit of frequency? Hertz (Hz)...
