Waves (Waves transfer energy. (waves can be classified by how the move…

- - - - the disturbance travels in a wave, transferring energy
  - - - same principle for water, dunking your finger and removing it causes an outward and an inward motion
  - - - the direction in which a wave travels is perpendicular to the direction of the disturbance
        
        rope, water wave
    - - the wave moves in the same direction as the disturbance
        
        sound wave
- - - - often measured in the number of crests that pass a point in one second
    - - as frequency increases, wavelength decreases this is bi-conditional
    - - transverse waves look like their graph, longitudinal waves don't
- - - - the bouncing back of a wave after it hits a barrier is reflection
        
        water at end of pool
        
        light off of a mirror
        
        sound off of a canyon wall
    - - refraction is the bending of a wave as it enters a new material at an angle other than 90°
        
        waves travel at different speeds in different mediums
        
        one side hits the thing first, and goes faster than the other side, bending the wave
      - example is cut or bent straw in a glass of water
    - - diffraction is the spreading out of waves through an opening or around the edge of an obstacle
  - - - constructive interference
    - - destructive interference
