A video lecture titled, ‘Planck’s distribution and Inverse square law’ from the e-learning course, ‘Introduction to Atmospheric Science’ developed by C Balaji, IIT Madras, for National Programme on Technology Enhanced Learning (NPTEL), India. These video lecture gives a detailed explanation about Planck’s Law for black body distribution. It also includes discussions on Wien’s displacement law, radiative loss, Simpson’s rule, Trapezoidal rule, Gauss quads, the Stefan-Boltzmann Law, and Newton Raphson method.
Students will learn about Planck’s law and how to calculate Earth’s temperature. They will also be introduced to photosphere, flux density, planetary albedo, reflectivity, absorptivity, transmissivity, emissivity for land, and emissivity of ocean which are used to calculate Earth’s temperature and determine its climate.
A transcript of the lecture is also provided.
Use this tool to help your students find answers to:
