1. 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
2. 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
3. What is amplitude?
From the middle line to the top or bottom of the arch to mark amplitude.

4. 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
5. 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)
6. 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.
7. What is the equation used in relation to waves?
• Distance     = Wave Speed   x    Time
• (Metres, M) =  (M/S)            x (Seconds, S)
8. 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
9. 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
