Waves transfer energy and information from one place to another. Waves can be defined in terms of:
The properties and applications of electromagnetic waves depend on their wavelengths. The electromagnetic spectrum is grouped into different regions from the longest wavelength group, , to the shortest wavelength group, . The human eye can see wavelengths of approximately 380 nm to 740 nm.
- , the maximum distance that a particle in the wave moves from its equilibrium position
- , the number of oscillations that occur per second. This is measured in .
- , the distance between two similar points on a wave
