1.15 A laser beam traveling through fog was observed to have an intensity of 1 (uW/m²) at a distance of 2 m from the laser gun and an intensity of 0.2 (u W/m²) at a distance of 3 m. Given that the intensity of an electromagnetic wave is proportional to the square of its electric-field amplitude, find the attenuation constant a of fog.
