Waves- Waves In Air, Fluids And Solids Flashcards
What are the two types of waves?
Transverse
Longitudinal
What is a transverse wave?
A wave for which the oscillations are perpendicular to the 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 traverse waves?
Electromagnetic waves
Seismic s-waves
Give two examples of longitudinal waves?
Sound waves
Seismic p-waves
What are the two types of longitudinal wave called?
Compressions
Rarefractions
What is a waves amplitude?
The maximum displacement of a point on a wave from its undisturbed position
What is the wavelength?
Distance from a point on a wave to the same position on the adjacent wave
Most commonly peak to peak or 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 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(m/s)= frequency(Hz) x wavelength(m)
What word is used to describe when a wave bounces off a surface?
Reflection
