  • P1.1 Radiation
    • Waves
      • Wave length is from one point in to the same point  on another wave
      • Energy is transferred in waves
      • The peak is the top of the wave
      • The trough is the bottom of the wave
      • The amplitude is the height of the wave
    • Electromagnetic Spectrum
      • From the longest wave length (Radio waves) to the shortest waves (Gamma Rays)
      • The order of the Electromagnetic Spectrum goes
        • Radio waves, Microwaves, Inferred, Visible Light, Ultra Violet, X-Rays, Gamma rays
      • Long wave lengths have low energy, low/no danger and a low frequency
      • Short wave lengths have high energy. they are highly dangerous and have a high  frequency.
    • Inferred Radiation
      • Every object emits inferred radiation.
      • The hotter an object is , the more  inferred radiation it give out in a given time
      • Inferred is used in thermal imaging
    • The green house effect
      • Short wave lengths can enter through the atmosphere.
      • Long wave lengths can't get out
