P12. Wave Properties Flashcards
What are the two types of waves?
- Transverse
- Longitudinal
What is a transverse wave?
A wave for which the oscillations are perpendicular to thw direction of energy transfer
What is a longitudinal wave?
A wave for which the oscillations are parallel to the direction of energy transfer
Give two examples of transverse waves
- Electromagnetic waves
- Seismic s-waves
Give two examples of longitudinal waves
- Sound waves
- Seismic p-waves
What are the two parts of a longitudinal wave called?
Compressions and rarefactions
What is a wave’s amplitude?
The maximum displacement of a point on a wave from its undisturbed position
What is wavelength?
The distance from a point on a wave to the same position on the adjacent wave
Most commonly peak to peak trough to trough
What is the frequency of a wave?
The number of waves that pass a given point each second
What is the unit used for frequency?
Hertz, Hz
What is meant by a frequency of 200Hz
200 waves pass a given point each second
What is wave speed?
The speed at which the wave moves or at which energy is transferred through a medium
What does a wave transfer?
Energy
State the equation used to calculate wave speed.
Wave speed = Frequency × Wavelength
What word is used to describe when a wave bounces off a surface?
Reflection
