P6 - Waves Flashcards
What do waves transfer?
Only energy in the direction they are travelling.
Not matter.
Define Amplitude.
The maximum displacement from the wave’s undisturbed position. (Height in m).
Define wavelength.
Distance between the same point on 2 adjacent waves. (m).
Define wave frequency.
The number of complete waves passing through a point per second.
Describe oscillations for longitudinal waves.
The oscillations are perpendicular to the direction of energy transfer.
Describe oscillations for transverse waves.
The oscillations are perpendicular to the direction of energy transfer.
Give 3 examples of transverse waves.
Most waves:
- Light
- Water
- Seismic S waves.
Give 3 examples of longitudinal waves.
- Sound
- Slinky
- Seismic P waves.
Give the formula that links wavelength, frequency and speed.
Speed = frequency x wavelength
