AI Thread Summary
Chromatic dispersion refers to the variation of an object's refractive index with different wavelengths of light. It is distinct from emissivity, which measures the energy radiated by an object. Understanding chromatic dispersion can aid in identifying which colors radiate more heat within a given spectrum. This phenomenon plays a crucial role in optics and materials science. Overall, chromatic dispersion and emissivity are fundamental concepts in understanding light behavior and thermal radiation.

can some one explain what chromatic dispersion is? and it helps me finding which colour radiates more heat in the given spectrum.

Dispersion is a different phenomenon from emissivity. Dispersion is simply a quantification of how the refractive index of an object changes with wavelength, while emissivity is a quantification of how much energy is radiated from an object.
 
Thread 'Question about pressure of a liquid'
I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...
I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
