What Makes Infrared Photography Different from Visible Light Photography?

AI Thread Summary
Infrared photography differs from visible light photography primarily due to the distinct wavelengths involved, with infrared capturing heat signatures rather than colors. While visible light reveals the colors of objects, infrared images display variations based on temperature, resulting in a unique appearance. Infrared cameras can penetrate opaque materials, making them useful for detecting individuals or objects obscured from view. This capability highlights the practical applications of infrared technology beyond artistic photography. Understanding these differences is essential for utilizing both techniques effectively.

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 can't explain it ..
 
Physics news on Phys.org
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.

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
