why can you look at the sun at sunset without burning your eyes?

Answer 1

the sun at sunset is red to orange in colour... this is because of a thing called refraction (bending of light)... its what happens when sunlight passes through water droplets in the atmosphere creating.... yes you said it... a rainbow. only at sunset the rays of the sun are refracted by the air in the atmosphere. the blues, greens and yellows are refracted (bent) more and are directed towars the ground... whereas the reds and orange colours are refracted less and hence get to reach your eyes...

so, the sun you see at sunset is not the sun in all its brightness but just a narrow range of the sepctrum of the sun's light... so its not that intense.. and you can look at it!

i also guess the fact that the light passes through more air and hence through more impurities in the air should also contribute to it not being so bright.

Answer 2

It has to do with the intensity of the sun and the amount of atmosphere filtering out the sunlight. When it is directly overhead, we have relatively 20+or- miles of atmosphere to filter out over 1million lumins of light. Conversely at sunset we have nearly 100+or- miles of atmosphere offering more filter for the 1million lumins. This is also why you can't look at the sun with binoculars or telescopes when it is directly overhead (unless you use a sun filter) but you can in the waining hours of the sunset.
It is said in space you cannot look directly at the sun or the intensity of the corona will burn your optic nerve at the rear of the eyeball. Good luck looking into the sun.

Answer 3

Sunscreen ought to be placed on approximately 10-20 minutes till now going out interior the sunlight. you should keep it properly faraway from the eyes, and place self assurance in a hat and/or sunlight colorations to guard the eyes. of direction, many youthful kiddos won't placed on colorations. A hat is high quality, even interior the pool. And, with the help of how, the temperature rather isn't an element. The air can nevertheless be cool, yet while it rather is obvious and sunny, you will get as lots of a burn as you may on a extra delicate day.

Answer 4

Much of the radiation is absorbed by the atmosphere. The light travels through a lot more air at sunset than at noon, which is why the sun appears red.

Answer 5

actually i will be doing sun gazing on the nov 24 together with divine cycle which will intesify energy expanding in each human sungazing is safe 1 hour after sunrize and hour before sunset but there is techqnique to do that u start at 10 seconds first day and each day u add 10secs till u reach maximum 44 minutes after 9 month with ur feet barefoot on the sand or soil for grounding after that u become ssolar battery and don't have to eat for rest of ur life and u become superman but it's more to that it's not for everybody with narrow minds uv ray it's not exceeding in point 2 ur under

Answer 6

You should never look directly at the sun even at sunset... because it is low on the horizon, the air is filtering more of the light and that's why it doesn't hurt as much but it is still damaging...

Answer 7

When the sun is low on the horizon there is a much larger part of the earth's atmosphere between it and your eyes. Conversely, when the sun is directly overhead there is substantially less atmosphere between you and it.
(do a quick sketch on a paper to "see" this concept)

The atmosphere absorbs that part of the light that hurts your eyes - so the more the better.

Answer 8

the sun is much further away at sunset so the damaging rays are absorbed by the atmosphere.

Answer 9

the lower the sun is in the sky, the more atmosphere the light has to pass through to reach your eyes. this difuses the harmful rays and makes the sun safe to view.

Answer 10

You cant. It is dim enough to let you look at the sun without pain but there is probably enough invisible light (infra red and ultra violet) to cause slow eye damage.
