N5 Physics Unit 1, Key - Coggle Diagram

- - - - speed (m/s) = Frequency (Hz) * Wavelength (m)
      - Frequency is the number of wavelengths per a unit of time (e.g. seconds minutes...)
      - Wavelength is the length between two reoccurring points in a wave (e.g. peak to peak or trough to trough)
      - Speed is how fast the wave travels
    - - period (s) = 1 / Frequency (Hz)
      - Period Is The Frequency (Number Of Wavelengths) In A Second.
    - - speed (m/s) = distance (m) / time (s)
      - distance is how far the full wave streches
      - time is how long it takes to produce the full wave
  - - - Smaller the gap, the more it bends/diffracts
      - Longer the wavelengths the more it diffracts
- - - - Micro Waves

        Absorbed Dose (Bq) = Energy (J) / Mass (Kg)
      - The Total Radiation Absorbed
    - - The Damage Of Radiation Caused
      - H = D x Wr
        
        Equivalent Dose (Sv) = Absorbed Dose (Bq) x Weighting Factor

  - - - Example: It takes 16 Hours To Half The Activity Of A Resource of 16,000 Bq what is It After 48 Hours. Answer: 2,000Bq
- - - - The Bending Of Waves As They Change Material
  - - - Ultra sound = Frequency over 20,000 Hz
        
        Humans CANNOT hear
      - Infra Sound = The Sound Below 20Hz
