Presentation
As a general rule: the longer the wavelength, the lower the frequency. Every colour has a specific frequency and wavelength. Only a small part of the electromagnetic spectrum is visible to the human eye. Violet has the shortest wavelength and red the longest. Behind violet is ultraviolet, which, although invisible to the human eye, can penetrate our body. Ultraviolet is responsible for tanning and has antibacterial properties. The longest wavelength is red. Behind red is infrared, which is invisible to the human eye.
