Waves Flashcards
1
Q
What is the rest position?
A
The undisturbed position of particles or fields when they are not vibrating.
2
Q
What is displacement?
A
The distance that a certain point in the medium has moved from its rest position.
3
Q
What is a peak in wave terminology?
A
The highest point above the rest position.
4
Q
What is a trough?
A
The lowest point below the rest position.
5
Q
What is amplitude?
A
The maximum displacement of a point of a wave from its rest position.
6
Q
What is wavelength?
A
Distance covered by a full cycle of the wave, usually measured from peak to peak, or trough to trough.
7
Q
What is the time period of a wave?
A
The time taken for a full cycle of the wave, usually measured from peak to peak, or trough to trough.
8
Q
What is frequency?
A
The number of waves passing a point each second.
