the distance between any two successive parts of a wave
Amplitude definition
the magnitude of the maximum displacement, or the maximum distance, from the particles equilibrium position
Frequency definition
the number of waves per second that pass by a given point during each second
Frequency formula
f=1/T
Period definition
the time for one complete wavelength to pass by a given point
Wave Speed formula
v=λf
Transverse wave:
the disturbance occurs perpendicular to the direction of travel of the wave. Example: wave on a stretched string
Longitudinal wave:
the disturbance occurs parallel to the direction of travel of the wave. Example: sound
Frequency range of the human ear:
20 Hz to 20 kHz
Principle of Superposition
At any time, the combined waveform of two or more interfering waves is given by the sum of the displacements of the individual waves at each point in the medium
