Chapter 12 - Waves 2 Flashcards
1
Q
Progressive wave
A
Wave that transfers energy from one point to another
2
Q
What is a longitudinal wave
A
Waves which the particle oscillates parallel to the flow of energy
3
Q
What is a transfer wave?
Examples…
A
Waves where the oscillations are perpendicular to the direction of energy flow
E.g. EM waves
4
Q
Definition of frequency
A
The number of waves passing a point per second
5

A
Distance between two adjacent corresponding points
6
Q
Amplitude
A
Maximum displacement of the wave
7
Q
Time period =
A
Time period = 1/frequency
8
Q
