Chapter 22, Problem 8P
An extended light source can be modeled as a group of several point-like light sources Figure P22.8 shows a linear light source (such as a fluorescent lamp) modeled by three point-light sources, a sheet of black paper, and a screen Copy the sketch in your notebook. Determine the regions of shadow and semishadow on the screen by drawing rays from the three point-like light sources. Qualitatively compare the relative brightnesses (or darknesses) of the regions.
