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.
Definition: Frequency is the measurement of the number of times that a repeated event occurs per unit of time. The frequency of wave-like patterns including sound, electromagnetic waves (such as radio or light), electrical signals, or other waves, expresses the number of cycles of the repetitive waveform per second.requency is the measurement of the number of times that a repeated event occurs per unit of time.
