Chapter 10, Problem Challenges 4

(choose chapter or problem)

Compute a rough estimate of the number of photons emitted eachsecond by a 100-W lightbulb. You might make the simplifyingassumptions that (1) all of the electrical energy is converted intoradiant energy and (2) the average photon that is emitted has anenergy corresponding to the peak of the BBR curve for an object at3,000 K (refer to Section 8.6).
