THE SCATTER OF LIGHT OF DIFFERENT COLOUR IN THE ATMOSPHERE

It is often claimed (devaux) that yellow light is superior to white light for vehicle headlamps. This claim is supported by evidence of a physical, physiological and psychological nature. In most cases, it appears that the advantages of yellow light are small, and can usually be neglected particularly when a comparison is made between yellow (filtered) and white (unfiltered) light for incandescent sources (schreuder). Our particular argument is related to the scatter in the atmosphere, notably in haze and fog. The present study gives a survey of the literature as far as relevant to this specific question.
