Worksheet: The Stefan–Boltzmann Law

In this worksheet, we will practice converting between the temperature of a blackbody and its radiant emittance using the Stefan–Boltzmann law.


A black body at 3,000 K radiates electromagnetic radiation with the peak intensity in the infrared range. A peak-intensity photon has a frequency of 3.10×10 Hz. What is the wavelength of this photon?
