• Astronomy & Cosmology

   Part 2 - Stellar Radii 

  How the radius of a stellar body is calculated in Astronomy & Cosmology is explained in this session.

  The following topics are developed:

       ♦ Stellar Radii in Astronomy

       ♦ Wien's Displacement Law

       ♦ Black body & Black-body Radiation Curve

       ♦ Calculating surface temperature (T) of a star using Wien's Displacement Law

       ♦ Peak intensity and λ_max of a star
   
       ♦ The Stefan-Boltzmann Law

       ♦ Calculating radius (r) of a star using the Stefan-Boltzmann Law

       ♦ Examples
