A wave in which the particle oscillations are parallel to the direction of travel.

What is meant by a Transverse wave?
A wave in which the particle oscillations are at right angles to the direction of travel.

What is meant by an unpolarised wave?
An unpolarised wave is a transverse wave in which the direction of particle oscillations keeps changing randomly but is always at right angles to the direction of travel.

How are sunglasses polarised?
When light reflects off a surface the light becomes polarised horizontally, sunglasses contain vertical filters which stop light from getting through, this is because the light is travelling in a horizontal position rather than vertical.

What is meant by Amplitude?
The maximum value of displacement of an oscillating particle from its equilibrium position.
5 of 11
What is meant by wavelength?
The minimum distance between two points on the wave oscillating in phase.
6 of 11
What is meant by Frequency?
The number of cycles of a wave that pass a given point in one second.
7 of 11
What is meant by Period?
The time taken for one complete cycle of oscillation.
8 of 11
What is meant by In phase?
At the same point in their oscillation cycles at the same time.
