What is meant by plane polarised light? What type of waves show the property of polarisation ? Briefly discuss polarisation by reflection.

Explanation

### Step-by-Step Solution:

1. **Definition of Plane Polarized Light**:
- Plane polarized light refers to light in which the oscillations of the electromagnetic waves are restricted to a single plane. This means that all the light waves vibrate in one specific direction rather than in multiple directions.

2. **Type of Waves that Show Polarization**:
- The type of waves that exhibit the property of polarization are **transverse waves**. In transverse waves, the oscillations occur perpendicular to the direction of wave propagation. This characteristic allows them to be polarized, as the oscillations can be confined to a particular plane.
