4.2 Travelling Waves Flashcards
1
Q
Types of Waves
A
Mechanical Waves
Electromagnetic Waves
Matter Waves
2
Q
Definition of a Wave
A
A disturbance which travels in a medium transferring energy and momentum from one place to another.
3
Q
Wavelength (λ)
A
The length of a complete oscillation (crest to crest/trough to trough)
4
Q
Speed of Wave (c)
A
c = λ/T or c = f x λ
5
Q
Movement Types of Waves
A
Transverse Waves
Longitudinal Waves
6
Q
Transverse Waves
A
Displacement is at right angles to the direction of energy transfer
7
Q
Longitudinal Waves
A
Displacement is parallel to the direction of the energy transfer
8
Q
Electromagnetic Spectrum
A
Goes from Radio waves to Gamma waves whilst increasing in frequency, but decreasing in wavelength.
