- - - - unit:
        μ0: T·m/A = N/A² (usingT=N/(A⋅m))
        ε0: F/m = C^2/(N·m²) (using F=C^2/N⋅m)
    - - Erms=1/√2 E0
        
        Brms=1/√2B0
  - - - total energy= (total energy density)* volume = u(ctA)
      - ϵ0=8.85*10^-12 C^2/Nm^2

- - - - sheet of insulating material that only transmits EM waves whose E field travel in transmission axis
      - can be use for any source of unpolarzied light to produce polarized light
      - S0=1/2 S(unpol)
    - - Another polarizer used to analyze the light that has passed through the first polarizer.
        
        It can be oriented at different angles to the first polarizer's transmission axis.
      - Malus' Law
        
        S=S0 * cos^2θ
        
        θ: angle between analyzer and polarizer
        
        mulit: S/So=1/2*cos^(2(n-1))θ
