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 'The Effect of Linear and Rotational Motion on Measured Weight'

Consider an extremely long and perfectly calibrated scale. A car with a mass of 1000 kg is placed on it, and the scale registers this weight accurately. Now, suppose the car begins to move, reaching very high speeds. Neglecting air resistance and rolling friction, if the car attains, for example, a velocity of 500 km/h, will the scale still indicate a weight corresponding to 1000 kg, or will the measured value decrease as a result of the motion? In a second scenario, imagine a person with a...

Thread 'Simple thought experiment with Stefan-Boltzmann law: energy'

Dear all, in an encounter of an infamous claim by Gerlich and Tscheuschner that the Greenhouse effect is inconsistent with the 2nd law of thermodynamics I came to a simple thought experiment which I wanted to share with you to check my understanding and brush up my knowledge. The thought experiment I tried to calculate through is as follows. I have a sphere (1) with radius ##r##, acting like a black body at a temperature of exactly ##T_1 = 500 K##. With Stefan-Boltzmann you can calculate...

Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (First part)'

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8 and stuck at some statements. It's little bit confused. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. Solution : The surface bound charge on the ##xy## plane is of opposite sign to ##q##, so the force will be...
