11.4 Diffraction & Polarisation Flashcards
1
Q
Define partially polarised
A
A transverse wave in which there are more oscillations in one particular plane but the wave is not completely plane polarised
2
Q
When does partial polarisation occur
A
When transverse waves reflect off a surface
3
Q
Define plane polarised
A
A transverse wave in which the oscillations are limited to only one plane
