6.6.1.2 Properties of Waves Flashcards
1
Q
What is amplitude?
A
- maximum displacement of a point on a wave away from its undisturbed position
2
Q
What is wavelength?
A
- distance from a point on one wave to the equivalent point on the adjacent wave
3
Q
What is frequency?
A
- number of waves passing a point each second
4
Q
What is the equation for a period?
A
- period = 1 / frequency
5
Q
What is a period measured in?
A
- seconds
- s
6
Q
What is frequency measured in?
A
- hertz
- Hz
7
Q
What is wave speed?
A
- speed at which energy is transferred (or the wave moves) through the medium
8
Q
What is the equation for wave speed?
A
- wave speed = frequency x wavelength
9
Q
What is wave speed measured in?
A
- metres per second
- m/s
10
Q
What is wavelength measured in?
A
- metres
- m
11
Q
What happens to velocity if frequency is increased?
A
- decreases
12
Q
What happens to velocity if wavelength is increased?
A
- increades
13
Q
What is the relationship between periodt and frequency?
A
- they’re inversely proportional
14
Q
What does a smaller period mean for frequency and velocity?
A
- higher frequency
- greater velocity
