Thermal Radiation Lecture Notes

Printer-friendly versionPrinter-friendly version

Some people are astonished to find out that all bodies warmer than absolute zero (-273oC) emit radiation. For example an average human emits about 300 W of thermal radiation. Why we do not notice it?  This will take a look at thermal radiation and how the wavelength and power emitted by a body depends on the temperature.
