The effect you will notice, is being able to see further, with less glare from the fog lighting things up in front of you. The reason for this is that the longer wave length of the amber (tending toward the red end of the visible spectrum) is refracted (bent)less by the fog droplets, and the light is scattered, not sent back to you by internal reflection within the fog droplets. I'm sure you all remember your physics teacher droning on about this, trying to make it all relevant. Yahh. Chuck Hill, former physics teacher |
