Direction of oscillation of electric field
Unpolarised light
All electric fields oscillate in same 2D plane
Reflection, scattering, polarising filter
Analyser
Square of amplitude: I∝A2I \propto A^2I∝A2
I=Imaxcos2θI = I_{\text{max}}\cos^2\thetaI=Imaxcos2θ
Parallel to polarisation plane (θ=0\theta = 0θ=0)
Perpendicular to polarisation (cosθ=0\cos\theta = 0cosθ=0)
Lux (1 lux=1 lumen⋅m−21 \text{ lux} = 1 \text{ lumen} \cdot \text{m}^{-2}1 lux=1 lumen⋅m−2)
