To solve the problem step by step, we will follow the principles of wave optics related to coherent light sources and their intensities. ### Step 1: Understand the setup We have two coherent monochromatic light sources located at two vertices of an equilateral triangle. The third vertex is the point where we need to find the resultant intensity. ### Step 2: Identify the intensity from each source The intensity due to each source at the third vertex is given as \( I_1 = 1 \, \text{W/m}^2 \) and \( I_2 = 1 \, \text{W/m}^2 \). ...
