Question

Problem 79.Beam 1 has an electric field amplitude of A1= 1000 N/C and Beam 2 has an electric field amplitude ofA2 =4 A1. A) What is the maximum possible measured irradiance if the two beams are combined at a detector. Under what conditions does this maximum measured value occur? B) What is the minimum possible measured irradiance if the two beams are combined at a detector. Under what conditions does this minimum measured value occur?
