If a scuba diver is in the sea when lightning strikes close, what could be the outcome.?
Answers:
Define close. If on the surface and within 40 M or so, you'll feel it, at least the hair on your head will. A direct hit is the same as on land, but the odds are with you still, only about 20% of people are killed in a direct strike.
A diver under? Likely not much if anything at all. The current from the strike travels on the surface and doesn't penetrate down.
The scenario is not likely to happen Ocean strikes are rarer than on land and no dive charter skipper is going to have his boat full of divers out in conditions like this.
if it hits the water he/she will be dead.
nothing happens to the diver because the water is too dense for lightning to actually do anything to the diver
Very good question :)
I've always believed that if water is hit by an electrical current any living thing in the water will be electrocuted.
If lightning struck in the ocean why doesn't everything in the vast area inhabiting that ocean get zapped?
I want to know the answer to this too.
Not an answer really but i liked the question. Keep em coming :)
good grief, i really don't know
wish i did.
nothing will happen.
If lightning strikes in a swimming pool, it can kill or injure swimmers. Fish in lakes or oceans could feel the effects of lightning, too. But the fish would have to be close to where the lightning strikes to be hit with enough electricity to get hurt.
Depends on how close when it strikes the water. I am sure
you will be tingled 20 feet away.
Well, if I remember correctly heat, therefor energy, travels 20 times faster in water than air. If you were in a small body of water then it would definitely kill, for instance a pool or the old hair dryer in the bath tub thing. The sea though is such a large body of water, and energy is dispersed so fast, that if lightening were to strike it would travel in all directions at once. I think you would have to be pretty close to the strike for it to actually kill you.
So basically it would depend on how close you were and how powerful the strike was but you would probably only get a mild shock however I think you'd probably be safer under the water than on the boat!
In a salt water environment, the conductivity of the water is sufficient to dissapate the charge easily. Unless the diver was in extremely close proximity to the strike he would not feel anything.
In a fresh water environment (lake, quarry, or river) the charge will seek the most conductive path (path of least resistance) as it disapates. This may include the diver's body, which is more conductive than the water. Still, proximity to the strike is necessary for the diver to be in the potential path of the charge.
