Longitudinal and transverse waves Flashcards
1
Q
What are longitudinal waves?
A
Where the oscillations are parallel to the direction of propagation
2
Q
What do we call the areas along a longitudinal wave?
A
Where the parkers are close together, we call a compression
Where the particles are spread, we call a rarefaction
3
Q
What are transverse waves?
A
The oscillations are perpendicular to the direction of propagation
4
Q
What are the maximum and minimum points also referred to as?
A
Peaks and troughs
5
Q
What is polarisation?
A
The restriction of oscillations of a wave to one plane
6
Q
What are the applications of polarisation?
A
TV aerials get the best reception when they point to the transmission source so they absorb the maximum amount of radio waves
