Wavelength refers to the distance between each peak or crest of a wave of light, heat, or other energy, and the next corresponding peak or crest. Generally speaking, the shorter the wavelength, the higher the energy. Although longer wavelengths have lower energy, up to a point, they have the ability to penetrate more deeply into skin and body tissue. Daylight, as you may recall from a long ago science class, is a combination of electromagnetic energy that is both seen and unseen.
