These exceptions include: 1  If a car behind you rear-ended your vehicle and pushed you into the back of another car. 2  Driver negligence, such as a car parked, broken down, or stopped with no warning lights. 3  A driver impaired by alcohol.
In mathematical terms, the frequency is the number of complete vibrational cycles of a medium per a given amount of time. Given this definition, it is reasonable that the quantity frequency would have units of cycles/second, waves/second, vibrations/second, or something/second. Another unit for frequency is the Hertz (abbreviated Hz) where 1 Hz is equivalent to 1 cycle/second.
1 Hertz is the unit of frequency, and just means how many cycles per second. 2  It is abbreviated as Hz. 3  It is named after Heinrich Hertz, one member of the Hertz family that made many important contributions to physics. 4  In formulas frequency appears as an  f .
