A python can detect thermal radiation from objects that differ in temperature from their environment as long as the received intensity of thermal radiation is greater than 0.60 W/m². Your body emits a good deal of thermal radiation; a typical human body has a surface area of 1.8 m², a surface temperature of 30°C, and an emissivity e = 0.97 at infrared wavelengths. As we've seen, the intensity of a source of radiation decreases with the distance from the source.
If you are outside on a cool, dark night, what is the maximum distance from which a python could detect your presence?
