2.4 The Nature of Waves Flashcards
1
Q
A progressive wave is
A
a disturbance or sequence of disturbances travelling through a medium, taking energy with it, but not taking the particles of the medium with it
2
Q
All mechanical waves
A
propagate in the same general way
3
Q
The particles in a transverse wave
A
are displaced at right angles to the direction of wave travel
4
Q
Examples of transverse waves
A
- Secondary waves
- Electromagnetic waves
5
Q
Polarised
A
Particle displacements are confined to just one o the possible directions at right angles to the direction of wave travel
6
Q
In a longitudinal wave
A
the particles of the medium are displaced parallel to the direction of wave travel
7
Q
Examples of longitudinal waves
A
- Primary waves
- Sound waves
