Waves - Coggle Diagram

- - - - This is why we see color
        
        Red apple= all wavelengths are absorbed except red, which is reflected
- - - - The line of the graph in the middle
    - - Highest point
    - - Lowest point
  - - - 1/2 the distance between crest and trough
      - More energy=larger amplitude
    - - The number of waves that pass a fixed point in a given unit of time
      - Frequency and wavelength are inversely proportional
      - Measured in hertz
      - A measure of energy
    - - a point on one wave to the same point on the next wave
      - Differences in wave length cause the difference in color of light
    - - Moves up and down perpendicular to the direction of the wave
  - - - Infrared Waves
        
        Visible Light
        
        Ultraviolet
        
        X-Rays
        
        Gamma Waves (highest)
        
        Example: radioactive rays harmful to living things
        
        Example: x-ray machines
        
        The sun emits UV rays
        
        ROY G BIV
        
        Warm objects emit infrared waves
      - Example: microwave ovens
- - - - Moves parallel to the direction the wave is moving
    - - Intensity (loudness) us caused by the amplitude, the higher the amplitude, the louder the sound
    - - Causes the pitch of a sound
    - - Varies continuously in amplitude and frequency
- - - - Travel faster in air than in water
  - - - travel faster in water than in air
- - - - Computer science pioneer, GPS software
    - - Developed a method to study the stars using sound
    - - Invented the foil electret microphone (the one used today)
    - - Developed alternative uses of laser, electron and ion beams to heat thermonuclear plasmas for use as alternative energy sources
