    Absolute Derivation
Click For Summary
The discussion centers on the Absolute Scale of Temperature as presented in SL Arora's Class 11 textbook. It highlights that this concept is essentially an application of Charles's Law, where the volume-to-temperature ratio remains constant at constant pressure. The temperature is expressed in degrees Celsius, necessitating the addition of 273.15 to convert to the absolute scale. This clarification helps in understanding the relationship between temperature and volume in gases. Overall, the connection between Charles's Law and the Absolute Scale of Temperature is emphasized.

TL;DR
I can't figure out the derivation of this formula.
It is from [ Class 11th] SL Arora, pg no. 11.3, the heading is [11.7] Absolute Scale of Temperature.

This is just Charles law (V/T is onstant at constant pressure), with T expressed in degrees Celsius, so you get (T+273.15) in the expression, instead of t

Plotted is the Irradiance over Wavelength. Please check for logarithmic scaling. As you can see, there are 4 curves. Blue AM 0 as measured yellow Planck for 5777 K green Planck for, 5777 K after free space expansion red Planck for 1.000.000 K To me the idea of a gamma-Ray-source on earth, below the magnetic field, which protects life on earth from solar radiation, in an intensity, which is way way way outer hand, makes no sense to me. If they really get these high temperatures realized in...
