Define the term 'displacement'
The direction/magnitude to which the wave has moved from its undisturbed position (How far above or below the x-axis
1 of 20
Displacement has both a direction and a magnitude therefore it is a ...quantity
vector
2 of 20
What is the symbol for displacement?
X
3 of 20
What is displacement measured in?
metres
4 of 20
Define Amplitude
The distance at which the wave has been displace/measurement from crest to x-axis or trough to x-axix
5 of 20
What is Amplitude's unit of measurement?
Metres
6 of 20
What is the symbol for amplitude?
A
7 of 20
Define Wavelengh
The distance from one complete oscillation to the next/from crest to crest/from trough to trough
8 of 20
What is wavelength measured in?
metres
9 of 20
What is the symbol for wavelength?
(upside down Y)
10 of 20
Define the term Period
The amount of time it takes for one whole complete wave cycle
11 of 20
What is the period measured in?
Seconds
12 of 20
What is the symbol for Period?
T
13 of 20
Define frequency
The amount of complete wave cycles that pass through a point or are transmitted by a source per second
14 of 20
What is frequency measured in?
Herz
15 of 20
What is the symbol for frequency?
f
16 of 20
Define Phase
The measurement of the position of a certain point along the wave cycle
17 of 20
Define Phase Difference
The amount by which on wave lags behind another wave
18 of 20
Give two ways in which you can measure phase difference
With angles(degrees and radians), in fractions of a cycle
19 of 20
Give the formula relating frequency to time period
f=1/T
