Waves are different, each one have its own properties and types, according to its nature and its own function. On 1801, an experiment was conducted by Johann Ritter, in order to study the existence of energy located beyond the visible ending of the visible spectrum.

For instance ultraviolet light affects many of the human organism parts and many diseases, but at the same time it does have disadvantages. Those harms are mainly related to biology; when exposing to overdose of UV-B&A we can notice that this will damage surface eyes and cells and it might cause cancer disease, although we have sunscreens that protect us from UV-B but still we have the free radical damage cause by the UV-A, some pretend that dark skin is in the safe side and protected from the harm, but after several studies, results showed that both are risked to
