Paper 15 Practical

LAB: Credit-1

Syllabus

Use C/C++/Scilab for solving the problems based on Statistical Mechanics like
1. Plot Planck’s law for Black Body radiation and compare it with Wein’s.
2. Law and Raleigh-Jeans Law at high temperature (room temperature) and low temperature.
3. Plot Specific Heat of Solids by comparing (a) Dulong-Petit law, (b) Einstein distribution function, (c) Debye distribution function for high temperature (room temperature) and low temperature and co mpare them for these two cases.
4. Plot Maxwell-Boltzmann distribution function versus temperature.
5. Plot Fermi-Dirac distribution function versus temperature.
6. Plot Bose-Einstein distribution function versus temperature.
