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.

Q1:

A black body at 3 0 0 0 K radiates electromagnetic radiation with the peak intensity in the infrared range. A peak-intensity photon has a frequency of 3 . 1 0 × 1 0 Hz. What is the energy of the photon?

  • A 1 . 6 0 × 1 0 J
  • B 9 . 6 0 × 1 0 J
  • C 7 . 0 2 × 1 0 J
  • D 2 . 0 5 × 1 0 J
  • E 2 . 5 0 × 1 0 J
