Final answer:
The period of a wave is the time taken for one complete wave cycle to pass a given point, represented by T and measured in seconds. It's inversely related to the frequency of the wave, which is the number of waves passing a point per second, measured in Hertz.
Step-by-step explanation:
The time required for one complete wave to pass a given point is known as the period of the wave. It is defined as the time for one complete cycle of the wave to occur, which consists of the wave starting at a certain point (like the zero point), reaching a crest, descending into a trough, and then returning to the start point again. The period is symbolized by the letter T and is measured in seconds (s). Furthermore, the frequency of a wave, represented by the Greek letter nu (v), is tied to the period, as it is the number of complete waves that pass a given point in one second, typically measured in Hertz (Hz). The wavelength, symbolized by the Greek letter lambda (λ), is the distance from one crest to the next and varies according to the type of wave, but it can be measured in meters, centimeters, or nanometers.
