Humans are mammals/animal which are very visual, We use our eye sight to detect much of the environment around us. What humans see is ‘’light’’, however what humans see is only a small part of the electromagnetic spectrum. Humans can only see the wavelengths of electromagnetic radiation between 380 and 769 nanometres this is only light though. Human eyes cannot not detect wavelength energy less than 380 or greater than 760 nanometres, so human cannot detect other energy such as gamma or radio waves. Electromagnetic radiation can be detected by rattlesnakes which use there infrared range ability do detect its prey.

The image below shows the wavelength for humans. its shown between the ultraviolet and infrared range which humans are able 2 detect:
