Frequency, also mentioned in the first paragraph, is the number of wave crests that pass one point in a period of one second. As well as a defined speed, every wave has a frequency. Frequency is measured in hertz (waves per second). For each type of wave, a longer wavelength means a lower frequency; a shorter wavelength means a higher frequency. Waves also have a defined period. Period is the time it takes for a wave to undergo one complete motion. The wave period is inversely proportional to the frequency – the longer the period, the lower the frequency.

Wavelengths, as mentioned before, are the horizontal distance between two adjacent waves. Every wave has a specific wavelength, but these vary widely between wave types – from hundreds of kilometres (tsunamis) to approximately a hundredth of a billionth of a metre (gamma rays). Wavelengths are usually measured from crest to crest. Or also from trough to trough.

There are two different kinds of waves, electromagnetic and mechanical waves. But they have some things in common. For instance, wavelength, frequency, period, speed, and amplitude. Wavelength is the distance, measured in the direction of propagation of a wave, between two successive points in the wave that are characterized by the same phase of oscillation. The wave crest and trough are like opposites. Crest is the highest point in a wave. While, trough is the lowest point in a wave. the absolute value of the maximum displacement from a zero (or a point of balance; resting position of particles or electromagnetic fields) value during one period of an oscillation. Frequency is the number of cycles or completed alternations per unit time of a wave or oscillation. All waves can be thought of as a disturbance that transfers energy.
