Infrared & Visible light

  • #1
Hi .. May i ask why does a infrared photograph of a person look different from a photograph taken from visible light ?


Relevant Equations :

V = ƒ x lambda



I believe it has got to do with the wavelength or frequency. However, i cant explain it ..

in visible light photograph you can see the colours but infrared works on heat signatures.

It shows different colors on the amount heat of the object its capturing

therefore infrared cameras are also used to search people covered by something. visible light cannot penetrate any opaque thing but infrared due to large wavelength penetrates it and can be see through cameras.
