what color light shines the brightest through fog?

Answer 1

I'm not too sure, but I would assume that it's green (532 nm), which is the most visible color for most humans.

Answer 2

the lower the FREQUENCY of a photon, the less times it orbits every second, so the less times it is subjected to the probability of being scattered or absorbed by a particulate such as a fog droplet.

for this reason, through fog, blue light is the least visible, and red the most visible. Infrared light penetrates even better, and radar, which is still photons, but at much lower frequencies penetrates better yet.

X-rays, which are extremely high frequency, penetrate matter due to their high energy, generally causing some damage.

Yellow is generally chosen for fog lamps because its the best compromise between penetration and human visual sensitivity where imaging is necessary.

Red is best in applications like warning lights on buildings and radio towers where distance is important.

In really dense fog, sound waves (which are not actually photons BTW) in the form of FOGHORNS are additionally used because they can travel better than light.

Answer 3

My understanding is that it is important for fog lights to be one color (rather than white, which is all colors) because the different
wavelengths(colors) of visible light scatter off the fog droplets
differently. This phenomenon is known as "dispersion," because the different colors of light in an image will separate from each other, causing the image to "disperse." If you illuminate the road with only one wavelength (color) of light, the images of the objects you see will still become somewhat blurry because of the scattering of light by the fog, but at least you won't have extra problems from dispersion. So, if we want to use just one wavelength of light, which wavelength should we use? It turns
out that light with short wavelengths scatters more than light with long wavelengths (short to long: violet, indigo, blue, green, yellow, orange, red). So, a long wavelength light will be best. There's another thing to consider, too: our eyes are not equally sensitive to all colors. It turns out that we are most sensitive to yellow and green light. So, our best compromise between sensitivity for our eyes and a long wavelength for least
scattering is yellow light. Now, I don't know what kind of light bulbs are used in fog lights, but another consideration used in street lighting is cost and efficiency. You may have seen some yellow street lighting in some places; this is "low-pressure sodium vapor" lighting. The special thing about this light
is that it is almost entirely one (actually two very close together)
wavelength of yellow light, and that it gives the most illumination for the amount of electricity. A big problem with this light, though, is that it throws off color perception. Under sodium vapor light, something blue looks gray. This makes it hard to, say, recognize your car in a parking lot.

Answer 4

Red, I think. Infrared light penetrates through gas and dust better than visible, but it depends on the nature of the gas. Water is opaque to anything below low infrared. But high energy light is more likely to penetrate and not be scattered.

Answer 5

I M GUESSING YELLOW BECAUSE THATS WHAT COLOR FOG LIGHTS ARE
GOD BLESS

Answer 6

definatly green because any other colour cannot be seen for 100 m
