  1. Transverse and longitudinal wavesA wave transfers energy from one place to another without transferring matter.
  2. Properties of wavesA wave can be described using four quantities.
  3. Types of electromagnetic wavesElectromagnetic waves are transverse waves, so their oscillations are at right angles to the direction the wave travels.
  4. Properties of electromagnetic waves 1When an electromagnetic wave meets a substance, the substance may absorb it, transmit it, reflect it or refract it.
  5. Properties of electromagnetic waves 2Changes in atoms and in the nuclei of atoms can generate or absorb electromagnetic waves over a wide range of frequencies.
  6. Uses and applications of electromagnetic wavesEach type of electromagnetic wave has uses that suit its properties.
