It is an illusion that water causes.
Quite so. The water in a swimming pool is cooler than body temperature (unless the swimming pool is actually a hot tub) and therefore, a person in that pool will lose heat by conduction.
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.
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.
Yes, the 130 volts you read on the bulb is the maximum it will handle. It will work perfectly on a 120 volt circuit and will actually last longer than a standard 120 volt bulb.
same as the bottom
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.
'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!
it depends on which swimming pool
What are swimming pool "Coopers"
