description of our subjective impression about the frequency of sound
the property of sound that varies directly with variation in the frequency of vibration
Amount of energy that a sound wave brings to a unit area every second.
objective - measured by instruments
when there is a force to pull it back to its starting position and enough energy to keep it vibrating
The cone-shaped disturbance created by an object moving at supersonic speed through a fluid.
when two tones of slightly different frequency are sounded together - it is that fluctuation in the loudness of the combined soudns
The V-shaped wave produced by an object moving on a liquid surface faster than the wave speed.
the interference that occurs when two waves combine to make a wave with a smaller amplitude
A frequency at which an elastic object naturally tends to vibrate, so that minimum energy is required to produce a forced vibration or continue vibration at that frequency.
the distance (measured in the direction of propagation) between two points in the same phase in consecutive cycles of a wave
