Black Body Demo: Box

This is a demonstration of the manner in which black body radiation can be produced by a box with a small hole. A body that absorbs all incident radiation emits black body radiation, which depends on its temperature. This demonstration was created at Utah State University by Professor Boyd F. Edwards, assisted by James Coburn (demonstration specialist), David Evans (videography), and Rebecca Whitney (closed captions), with support from Jan Sojka, Physics Department Head, and Robert Wagner, Executive Vice Provost and Dean of Academic and Instructional Services.
