4.4.6-Polarisation

Flashcards do conjunto (4)
- 1Only transverse waves(including electromagnetic waves) can be polarisedbecause longitudinal waves do not have oscillations at right angles to their direction of travel. The oscillations of these waves are in line with the wave's direction of travel.

- 2—unpolarised- the electric field can be in any number of planes.
plane-polarised wave- a wave that has fields only in one plane.
- 3In a Plane-polarised wavethe oscillations of the field and the direction of the travel are confined to a single plane.
- 4A polarising filterproduces plane-polarised light by selective absorption of one component of the incident oscillations - the filter transmits only the component of light polarised perpendicular to that direction.
