Q

Diffraction

A

When a wave “expands” to cover more area.

Higher diffraction happens when a wave’s wavelength is equal to or smaller than the gap thorugh which it passes.

Q

Polarisation

A

Only applicable to transverse waves as they oscillate in both the electric and magnetic fields, which are normally to each other. This is because polarising a transverse wave will allow an oscillation from either field to get pass through, whereas a longitudinal wave not.
