Science IS: Waves

1. Types of waves

   • Transverse
     • Transverse waves are waves that have an up and down movement and the direction of travell is at 90 degrees to the undulations
   • Longitudinal
     • Longitudinal waves are waves that have vibrations moving in the same direction as the direction of travel

2. Superposition

   • Superposition is when two waves meet and they affect each other.

3. Waves in step

   • If waves meet in step they will add together, increasing the amplitude

4. Waves out of step

   • If waves meet out of step they subtract, cancelling each other out.

5. Sound Waves

   • Sound waves are produced by all vibrating objects.
   • Sound travels fastest in a solid
   • Particles can pass energy on quickly because they are arranged in a regular pattern and are tightly packed.
