Step 1
What is meant by polarisation?
Answer
Polarisation refers to the phenomenon in which the oscillations or vibrations of a transverse wave occur in a specific direction. In a transverse wave, the movement of the wave medium is perpendicular to the direction of wave propagation.
When a transverse wave is polarised, it means that its oscillations can be restricted to a single plane. For example, light waves can be polarised, allowing them to vibrate in only one direction rather than in all directions. This selective restriction of oscillation directions is what defines polarisation.
