Chapter 33, Problem 008 Assume (unrealistically) that a TV station acts as a point source broadcasting isotropically at 2.7 MW. What is the intensity of the transmitted signal reaching a nearby star that is 27 ly away. (An alien civilization at that distance might be able to watch X Files.) A light-year (ly) is the distance light travels in one year. Number Units the tolerance is +/-2% Click if you would like to Show Work for this question: Open Show Work
