Physics (Waves (There are some important words to describe a wave: (There…

- - - - Examples of Longitudinal waves:
    - - Examples of Transverse waves: electromagnetic waves (e.g. light), ripples on the surface of water
  - - - V = f λ or Velocity = Frequency x Amplitude
- - - - Convection is when hotter areas of a fluid are less dense and rise upwards. They are replaced by colder more dense fluid from above
      - Radiation is given off by all objects with a temperature above absolute zero. Thermal energy is transferred via infrared radiation. Some will be absorbed, some will be reflected and some will be transmitted.
      - Conduction is when more energetic particles near the heat source vibrate more. These vibrations are passed on to the neighbouring particles. Metals are good thermal conductors
