Be sure that you play with the two student exercises so that you understand Planck's distribution formula.



  1. Follow the instructions at Web Physics 320 Lab.

Data Handling

  1. Use the data handling instructions with the lab procedures.


  1. Describe your experiment in sufficient detail that another similarly equipped student could perform your tests.
  2. IOnclude your assessment that the light bulb acts/doesn't act as a blackbody over various temperature ranges.
