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.
The unit of frequency is the hertz. The period (T) of a wave is the time that it takes for one complete oscillation. The unit of period is the second. The period and frequency of a wave are linked by the following relationship, The speed (v) of a wave is the distance travelled per unit time by the wave.The unit of speed is the metre per second, m s -1.The speed, frequency and wavelength of a wave are linked by the following relationship,he period and frequency of a wave are linked by the following relationship, The speed (v) of a wave is the distance travelled per unit time by the wave. The unit of speed is the metre per second, m s -1.
