The maximum displacement of the medium from the rest position is known as this
What is amplification?
This is the Greek letter used to designate wavelength in the wave speed equation
What is lambda?
This is an indication of how high or low a sound is as determined by the frequency of the sound wave

When the vibration of the medium is parallel to the direction the wave travels, the wave is knows as this kind
What is a longitudinal wave?
This is the distance between a point on one cycle of a wave and the same point on the next cycle
What is wavelength?
The rate at which a wave's energy flows through a given area is known as this
What is intensity?
This term describes sound waves with frequencies above 20,000 Hz
