Everything about Negative frequency
Indication of rate and sense of rotation
In mathematics, the concept of signed frequency can indicate both the rate and sense of rotation; it can be as simple as a wheel rotating clockwise or counterclockwise. The rate is expressed in units such as revolutions per second (hertz) or radians/second. Wikipedia →
