Can the sun's rays reach you underwater? |
I have a pool float that is mesh so most of your body is about an inch underwater when you're on it. Is it possible to get sunburned or tanned when in this float? the sun's rays are actually amplified by the water and you will burn twice as fast. it has to do with the polarization being increased by the wavelength of the uv and beta rays. you need to be at least 3 feet under water - at which point you will drown so therefore that won't benefit your relaxation. yes you can get tan and burn but ive never had this problem being already pretty dark. i also know that the part above water will burn quicker because it absorbs both the rays that hit your body and the rays that are reflected from the surface. as for the parts under water i dont think they burn as fast because currents in the water absorbs some of the rays converting it to heat and the motion of water shifts rays moving through it the suns rays are stronger when you are in water if you want a good tan the best place to be is in water but not for too long or else you may burn judging from all the plant life under water, i think you can infer that the sun's rays do indeed penetrate water, and for a a fairly good distance. UV rays (the rays that tan and burn your skin) are relatively unaffected by the first foot or so of water. some would say that they are even intensified, but in fact your are simply getting them focused and reflected thus receiving more of them while only a few inches underwater. i swim in the middle of the day for an hour, 3 or 4 times a week. there is almost nothing i can do but tan no matter how much sunscreen i put on. if you are susceptible to the sun (i.e. fair skinned,) keep that sun block on and re-apply often. 34 years of competitive simming, 20 years teaching, coaching, lifeguarding thats a good question cause i know what kinda float your talking about. but from my point of view i always thought you could never got sun rays behind glass or underwater. I'm a swimmer and a certifed scuba diver. Olympic size diving pool are 5 meters deep, and that's not enough ot block to the sun. You need to get at least 30 feet deep for the stop to stop reaching you. At 60 feet, there's no more sun and it's all dark. |
