Photons
Cards in this deck (5)
- 1At what speed do electromagnetic waves travel in a vacuum?300000000 m/s
- 2What makes up an electromagnetic wave?An electromagnetic wave consists of an electric wave and a magnetic wave which both move in phase at right angles to the direction of travel.
- 3What is a photon?A photon are energy. They are released when there is to much energy in a shell (particle) and move to one of a lower energy.
- 4How do we work out a photons energy?Photon energy = Planks constant x frequency
- 5What equation works out the power of a beam?Number of photons x planks constant x frequency.
