amplitude : the maximum displacement of the energy from it's mean value is called amplitude .unit is meter.
pitch : pitch is a non-measurable quantity, having a relative character , more the frequency more the pitch and vice-versa
frequency : number of oscillation per seconds is called frequency .unit of frequency is Hertz i.e. Hz
time period : time taken to complete one oscillation is called time period. unit is seconds.
echo : a sound caused by the reflection of sound waves from a surface back to the listener is called an echo
oscillation : oscillation is also defined as wavelength i.e. the distance between 2 successive/ compression/rarefaction/trough/crest is called as wavelength .unit is lamda.
