So assuming only conduction, heat will travel proportionately based on thermal conductivity (higher thermal conductivity means more heat traveling via that path).
Thanks for your responses!
Hello,
What "path" do objects take to reach thermal equilibrium? Does heat from a hot part sitting in room temperature air like to travel through the most thermally conductive portions? My thought is that it is similar to current in a circuit taking the path of least resistance (where the most...
I understand that when light goes between air and water, refraction occurs (either towards or away from the normal). If the light going between air and water is already going in the same direction as the normal, is there no refraction (or a refraction angle of 0 degrees)?
Thank you.
I don't have a reference, I guess it is just something I have heard from peers.
After having done a little more research, it seems like the color of the lighting should be the opposite of the color of the object you are trying to image in order to make the object stand out more. That being...
Hello,
I have heard many times that red lighting is good for imaging applications where the effect of ambient light needs to be reduced to a minimum. What is the theory behind this? Why does red light (vs. other colors) reduce the effect of ambient light?
Thank you.
Thanks a lot for your response. After looking up those terms, I understand that specular reflection happens on smooth surfaces, and diffuse reflection happens on rough surfaces. What I am still confused about, however, is the difference (from the perspective of a camera) between emission and...
Hello,
I was wondering how one would be able to tell the difference between an object emitting a certain wavelength of the EM spectrum, vs. an object reflecting that same wavelength of the EM spectrum. For example:
1) Suppose I have an IR source at 7 microns. I point this source at water, and...
