Waves In Air, Fluids And Solids Flashcards
What are the two types of waves?
Longitudinal and transverse
What is a transverse wave?
A wave for white the oscillations are perpendicular to the direction of energy transfer
What is a longitudinal wave?
A wave where the oscillations are parallel to the direction of energy transfer
Give 2 examples of transverse waves
Electromagnetic
Seismic s-waves
Give 2 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 form a point on a wave to the same point on the next wave
What is the frequency of a wave?
The number of waves that pass a given point each second
What is the unit 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
What does a wave transfer?
Energy
State the question used to calculate wave speed
Wave speed= frequency x wavelength
What word is used to describe when a wave bounces off a surface?
Reflection
