Polarisation Flashcards
What is wave polarisation
Restriction of a wave so it can only oscillate in a single plane
Which waves can be polarised
Transverse
What is the effect of a polarising filter on light waves?
allows only waves with a plane in the safe direction as the filter’s plane to pass through.
Where can you find polarising filters?
Sunglasses
What happens to unpolarised light when it passes through a polarising filter?
It becomes polarised along the axis of the filter.
True or False: Polarisation can only occur in light waves.
False: Polarisation can occur in other types of waves, such as sound waves.
Fill in the blank: ________ is the process by which a wave’s polarisation state changes.
Polarisation rotation.
What is the relationship between polarisation and wave frequency?
Polarisation does not depend on wave frequency; it is a characteristic of the wave’s oscillation direction.
