To find the distance d over which a signal can be seen clearly in foggy conditions, a railways engineer uses dimensional and assumes that the distance depends on the mass density p of the fog, intensity(power/area) S of the light from the signal and its frequency f. The engineer finds that d is proportional to [...]
