The goal is to determine the fraction of maximum power radiated at a specific angle (30\u00b0) and its relationship to the wavelength. The correct answer indicates that at this angle, the fraction of maximum power is 3/4, and the dependence on wavelength is \u03bb^(-6), highlighting the intricate relationship between radiation characteristics and geometric factors."}
