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.
Unit of measuring frequency is Hertz (Hz), and âFâ is the most common symbol used in physics to denote frequency. Relation of frequency and period is given by F = 1/T (or T = 1/F). For example, period of 88MHz FM wave is T = 1/F =1/88Ã106 = 11.3x 10-9 s = 11.3ns (nanoseconds).
