Planck Distribution Plot

Overview

This is a demo experiment that shows the Planck distribution versus wavelength as a function of temperature. The intent is to allow someone to see what the spectral distribution is from a black-body radiator at a given temperature. Programmers can also make use of the Planck distribution functions in the procedure file (wavelength and frequency forms are given).

Features

A graph shows ten radiation curves in the wavelength range 200 nm to 1200 nm. A frequency axis is given at the top, and a rainbow window is included in the graph to show the range of visible light.

A panel input allows you to change the lower temperature and step size of the ten curves.
