the primary difference between infrared and visible light is that
Visible light is visible (for the human eye), infrared is not. Infrared has a longer wavelength, and a higher frequency. visible light is visible to human i.e the VIBGYOR, aboâ¦ve vibgyor are ultravoilet light which is not visible to human eye and below vibgyor are infrared light which is also not visible to human eye.
Infra-red light has a longer wavelength and lower energy than visible light.
