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.

∙ 9y agoThe bottom of a pool appears further away than it is because of the way that light bends when it enters water. This is called refraction and it is the change in direction of a wave due to a change in the medium it is propagating through. This also effects the speed at which light propagates.

∙ 9y agoThe bottom of a pool appears closer than it actually is because of the effect of light striking the water. Light is slightly bent as it moves through water and this creates the impression that the bottom is closer.

A swimming pool, a kilolitre
Figuring out cubic ft in a swimming pool?
Assuming the swimming pool is a rectangular block, just multiply length x width x height. If these measurements are in feet, the volume will be in cubic feet.If the swimming pool has parts that are deeper than others (it is common to have a shallow part, for children who don't swim well yet), calculate the volume for each part separately, then add the results.Assuming the swimming pool is a rectangular block, just multiply length x width x height.

A thimbleful of water at 100c has a highrer temperature than a swimming pool full of water at 20c but the pool has more thermal energy than the timble explain?
To raise the temperature of water in a thimble of water from 0 to 100 requires a small amount of thermal energy. To do the same with a swimming pool would require putting a huge amount of thermal energy into the water comparatively speaking.
Why it is so easy to swim in sea water than swimming pool?
Sea water contains lots of dissolved salts. Thus the density of the salty sea water is more than that of water in swimming pools, and the salty water lifts you more than fresh water, which make swimming easier.
Why can't I stay on the bottom of my swimming pool when I go under water?
b/c you're less dense than the water (likely due to the gas in your lungs).
How a swimming pool looks shallower than it actually is?
It is an illusion that water causes.
A swimming pool appears shallower than it is because of?
This is because of the refraction of the light when it hits the water.
Why water in a rock pool often appears to be much shallower than it is?
Because the light is refracted and so the water appears shallower than it is Because the light is refracted and so the water appears shallower than it is
Why does the water in a swimming pool look more shallow from the outside than when you step in?
This phenomenon occurs due to the refraction of light as it travels from the air into the water. When light enters the water at an angle, it changes speed and bends, causing objects beneath the water's surface to appear shifted and closer to the surface than they actually are. This refraction effect makes the water appear shallower when viewed from the outside.
Why do rivers appear shallower 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.
Is swimming in the sea healthier than swimming in the swimming pool?
One is not necessarily more healthy than another, because it depends on the sea and it depends on the swimming pool. Ocean conditions vary tremendously depending on the weather, currents, and other variables. When evaluating the health of a swimming pool, you need to look at how well it's maintained. A sanitized swimming pool (usually with chlorine) that is balanced (meaning pH, alkalinity, calcium hardness, etc.) is safe for swimming. If the pool hasn't been properly sanitized and balanced, swimmers are vulnerable to ear and eye infections and other problems caused by bacteria and other contaminants in the pool.
Will a deeper inground swimming pool have colder water than one that is shallower and is there a way to calculate the impact on water temperature of various pool depths without heaters?
In theory, yes it does make a difference. However, the practical reality is that in many climates (like Texas), the pool will warm sufficiently to use without a heater for most of the year.
The area of a swimming pool is 200 squaare feet the length of the pool is 10 feet longer than the width What is the length of the swimming pool?
length = 20

20 ft
Why swimming pool appears shallower than its real depth?
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.
The area of a swimming pool is 200 square feet The length of the pool is 10 feet longer than the width What is the width of the swimming pool?
The width of the swimming pool is 10 ft because 10*(10+10)=200
What does piscina mean in spanish?
swimming pool = alberca (ahl-BER-kah). Some people use the word piscina, but piscina is more of a (fish) pond than a swimming pool.
