Worksheet: The Wien Displacement Law

In this worksheet, we will practice using the Wien displacement law to relate black body temperature to the wavelength of peak emission intensity.


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 energy of the photon?

  • A2.05×10 J
  • B9.60×10 J
  • C1.60×10 J
  • D7.02×10 J
  • E2.50×10 J
