Understand that for a constant wave speed the wavelength of the wave is inversely proportional to the frequency.
For a constant wave speed the wavelength of the wave must be inversely proportionate to it's frequency
-
The equation to calculate Wave Speed, Frequency and Wavelength of the Wave.
- Wave Speed = Frequency x Wavelength
- M/S = Hertz, HZ x M
- V = F x λ
-
What is amplitude?
From the middle line to the top or bottom of the arch to mark amplitude.
-
What is wavelength and how is it calculated?
- The wavelength of a wave is the length of one wave.
- It is calculated using the equation;
- Wave speed ÷ Frequency
- V ÷ F
- M/S ÷ Hz
-
What is frequency and how is it calculated?
- Frequency is the number of waves passing through a point each second.
- It is calculated using the equation;
- Number Of Waves
- Time
- 1 wave per second = 1HZ
- Frequency is measured in Hertz (HZ)
-
What is a Wave?
A wave is a disturbance, caused by a vibrating source, that transfer energy in the same direction as the wave is travelling without transferring matter.
-
What is the equation used in relation to waves?
- Distance = Wave Speed x Time
- (Metres, M) = (M/S) x (Seconds, S)
-
What are transverse Waves?
In a transverse wave, the particles vibrate at right angles to the direction of the wave's movement.
Eg. Water Waves, S Waves, EMW Waves
-
What are longitudinal waves?
In a longitudinal wave, the particles vibrate in the same direction as the the moving of the wave.
Eg. Sound Waves, P Waves
