It is an illusion that water causes.
Yes, your body can lose heat by conduction while in a swimming pool. Conduction is the transfer of heat through direct contact with a cooler surface, such as the pool water, causing your body temperature to drop.
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.
One efficient way to heat a swimming pool and maintain comfortable temperatures for swimming is to use a pool heater. Pool heaters can be powered by electricity, gas, or solar energy, and can quickly raise the water temperature to a desired level. Additionally, using a pool cover when the pool is not in use can help retain heat and prevent heat loss, further ensuring comfortable swimming temperatures.
When looking down into a swimming pool, you are likely to overestimate its depth. This is because of the way light refracts in water, making objects appear closer to the surface than they actually are.
Due to the refraction of light, a body of water (whether its a sink, pool or lake) will appear more shallow than it actually is.
This is because of the refraction of the light when it hits the water.

Actually there is a website that has been developed to help swimming pool owners and guide them on proper swimming pool maintenance. The website is called Best Swimming Pool Guide and can be located at: http://bestswimmingpoolguides.com/
When ever it looks like it needs it, It depends largely on the nature of the dirt getting into the pool.
There are many different jobs associated with a swimming pool. A lifeguard watches out for swimmers, a pool boy or cabana boy serves drinks and cold washcloths to sunbathers, and there is also a maintenance crew involved with keeping the swimming pool clean and functioning properly.
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.
'Swimming Pool', sometimes shortened to 'Pool'.
Is it an indoor pool or outdoor pool? Have a qualified swimming pool tech, a swimming pool inspector or a swimming pool consultant advise you through an inspection of your pool. They will find and actually visually see things that stand out as needing attention or repairs or adjustments. Those things I cannot do over the internet. k
Red or pink algae in a swimming pool is actually a bacteria. The most common cause is contamination from swimming suits when going from the ocean to the pool. Chlorine is the most effective treatment. Algae products will not work because it is not a true algae.
The dimensions of the pool are needed to calculate this Well actually depends how big and how much u put in to it!
What are swimming pool "Coopers"
it depends on which swimming pool
