idk thats why i asked duhhh
Either you can swim, or you can't. Swimming is done close to the Surface of the water. How deep it is doesn't really matter once you can't touch bottom.
Due to refraction. When light travels through a denser substance, it bends towards the normal, so things appear to be at a different angle, size or depth than they really are.
It's not where it appears to be because the sun's rays are reflecting off of the water surface, and the water surface are bending the rays, so it looks like the coin is somewhere else.
think of it the same way. normally the high is on top and the low is on bottom. so when it would be hot it would be closer to the top, and when the temp. is low, it would closer to the bottom. just think of it the same way to read it. whenever the low temp is closer to the top it's really cold. if the temp ceases to the bottom, it's getting hot. hope this helps :)
They're born in the water, so pretty much immediately. The mother may help them to the surface at first, but they really need to start swimming right away.
Objects underwater appear closer than they actually are due to the refraction of light. Light bends as it passes from water to air, making objects underwater appear closer to the surface than they really are.
Let us consider an object 'O' at the bottom of a river/swimming pool. Light speeds up as it travels from water to air. So, the ray is bent away from the normal. As a result for an observer on the shore, it appears as if the rays are coming from a point 'I', which is just slightly above the bottom of the surface That is why rivers and swimming pools seem shallower than they really are.
They curl up in a ball and sink to the bottom of the sea to keep warm. The sea bottom is really warm so that is what they do ! They do not do that because they must come to the surface for air!
refraction of light produces the shallow swimming pool illusion. As you look down at a pool, you are seeing light that has changed angle as it moves out of the water and into the air. Specifically, light moves faster through air than water. Light coming up from the bottom of the pool refracts down to arrive at your eyes at a shallower angle. You see the bottom of the pool a little higher and farther away than it actually is.
no not really i dont think there is a swimming pool consert.
This phenomenon is due to light refraction. Light waves bend as they move from one medium to another of different density, such as from air to water. As a result, objects underwater may appear closer to the surface or deeper than they actually are when viewed from above water.
No you can't. That is an urban myth. You can not get a cramp from eating before swimming.
