Wave motion Flashcards
In a longitudinal wave where the points are:
close together, its called
compressions
In a longitudinal wave where the points are spaced apart, its called
rarefactions
Examples of longitudinal waves are
NAME?
Amplitude is defined as
The distance from the undisturbed position to the peak or trough of a wave
Amplitude is given the symbol __ and is measured in __
symbol A
measured in metres
Wavelength is defined as
The distance from one point on the wave to the same point on the next wave.
In a transverse wave
the wavelength can be measured from
one peak to the next peak
In a longitudinal wave
The wavelength can be measured from
the centre of one compression to the centre of the next
The wavelength is given the symbol __ and is measured in __
symbol λ (lambda)
measured in metres (m)
Frequency is defined as
the number of waves passing a point in a second
The time period of a wave is defined as
The time taken for a single wave to pass a point
The time period is given the __ and is measured in __
symbol T
measured in seconds (s)
What is the formula for frequency
f = 1/T
f : frequency in Hertz
T : Time period in seconds
