What’s the two things that waves transfer?
Energy and information
What do waves not transfer?
Matter
What is a longitudinal wave?
The ossification are parallel to the direction of energy transfer
Describe a transverse wave
The oscillations are perpendicular to the direction of energy transfer
Give an example of a longitudinal wave
Sound waves
Give an example of a transverse wave
Ripples on the surface of the water
For a longitudinal wave what name is given to a region where the particles are close together?
Compression
What is the e name for maximum displacement on a point of a wave from the equilibrium position?
Amplitude
What is the name for the distance from a point a point on a wave to the equivalent point on the adjacent wave?
Wavelength
What is the name for the number of complete waves past the same point in one second?
Frequency
What are the units for frequency?
Hertz (Hz)
What is the name for the time taken for one complete wave to pass a point?
Period
What are the units for period?
Seconds (S)
What is the definition of wave speed?
The speed at which energy is transferred through the medium
Which equation can be used to measure the speed of sound using wooden blocks?
Barge speed = speed/time
What two measurements would you need to take to calculate the speed of sound in air?
Distance and time
What is it called when a sound wave is reflected?
An echo
