Visible spectrum. The visible spectrum is a very small portion of the electromagnetic spectrum that can be seen by human eyes. This is shown in the figure below, which is not to scale. The exact boundaries of each type of wave are not precisely defined and often different authors have slightly different values.he limit between ionizing and non-ionizing radiations is located somewhere in the UV region, but it's not clearly defined and somehow fuzzy. A photon energy of 10 eV (corresponding to 124 nm) is often considered the threshold between ionizing and non-ionizing radiation, but there is no consensus on this topic.
