The eye detects visible light, the nerves detect infrared or heat and the skin is sensitive to ultraviolet ( tanning and sunburn ) and the lens of the eye develops cataracts in response to UV also. a human body can detect ionizing electromagnetic radiation, if he can see what his geiger counter is reading.
The human eye is most sensitive to light with wavelengths between 400 nm (blue) and. 700 nm (red). Any âlightâ with wavelengths longer than 700 nm is called infrared and is. not normally visible (except sometimes as a dull deep red). Devices used for OW systems. usually operate in the ânearâ infrared region between 700 nm and 1000 nm.
