e980ad09bac141568575f9474bc1ac0bWhat is polarisation?
Where particles in a wave are oscillating in one direction only.
cee7caa3cee9443d96e83759a524a47eWhat does it mean for a wave to be plane polarised?
Where the particles in the wave are oscillating along a single plane.
f92d32dcd65c41cd86eebb12f1f682aaWhat does it mean for a wave to be partially polarised?
Where most of the particles in a wave are oscillating along a single plane.

Only allow oscillations that are in a certain direction.

Because you can’t polarise a longitudinal wave.

It is the opposite to what you’d expect.

Because the waves are absorbed when they cause charges going up and down the filter.
