(المسافة الموجية)
طول الموجة
the distance between a point on a wave of energy and a similar point on the next wave
Wavelength refers to the distance between two consecutive peaks or low points of a wave, typically measured in meters. In terms of radio, television, or light waves, it determines the size of the wave and is closely related to the frequency. A longer wavelength corresponds to a lower frequency, and a shorter wavelength corresponds to a higher frequency. Wavelength affects how waves travel, with longer wavelengths able to travel further and penetrate obstacles more easily, while shorter wavelengths offer higher resolution but may not travel as far.
