Infrared cameras detect energy in which range?

Explanation:
Infrared cameras sense heat radiation, not visible light. Objects at typical temperatures emit infrared energy, and these cameras are designed to detect that part of the spectrum. Long-wave infrared cameras commonly operate roughly in the 7.5 to 14 micrometers range, which aligns with the peak thermal emission of many everyday objects. The visible range is much shorter, ultraviolet is even shorter, and microwaves are much longer, so those ranges aren’t what infrared cameras detect. This is why infrared imaging shows temperature differences and heat patterns in a scene.
