Understanding Body Heat Wavelength: FAQ and Applications

AI Thread Summary
Body heat primarily emits infrared radiation, with wavelengths typically ranging from about 700 nm to 1 mm, which is indeed above the visible light spectrum. Infrared cameras often utilize Avalanche Photo Diodes (APDs) for detecting this radiation, enhancing sensitivity in low-light conditions. The discussion also touches on the suitability of APDs for visible light detection, given their capability to sense a range of wavelengths. Additionally, there is a philosophical inquiry about the relationship between mass, energy, and the ability to control matter through mental processes. Understanding these concepts can bridge the gap between physical phenomena and human perception.

Can someone explain to me what is the wavelength of body heat?

Since visible light is between 400nm - 700nm. Is body heat wavelength above 700nm?

What is the wavelength range of body heat in respects to nm or m?

And lastly are Infrared cameras made with Avalanche Photo Diodes? like the one attached?

Also i have a question about current arcing. Since arcing is visible would a avalanche photo diode be suitable for visible light as well?

If mass and energy are the same why can we mentally control matter?
 
or can't control matter?
 
You can. I am doing it as I type this...mentally controlling my fingers.
 

Thread 'Condensate rate of water for an air conditioning cooling coil'

I need to calculate the amount of water condensed from a DX cooling coil per hour given the size of the expansion coil (the total condensing surface area), the incoming air temperature, the amount of air flow from the fan, the BTU capacity of the compressor and the incoming air humidity. There are lots of condenser calculators around but they all need the air flow and incoming and outgoing humidity and then give a total volume of condensed water but I need more than that. The size of the...

Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'

Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...
