Question: what is the difference between ultraviolet visible and infrared radiation?
Answer: The infrared has longer wavelengths (700 nm to 1 mm) than those of visible lights (390 nm to 700 nm). Note though that visible light is the only radiation that can be seen by the human eye. The ultraviolet is much more intense and has a shorter wavelength (400 nm to 10 nm) compared to visible light.
