What can you do with an old satellite dish?
-- construct a bird-bath -- construct a squirrel feeder -- polish the concave surface and construct a solar burger-and-dog cooker No batteries or electronics are required for any of these 'downstream applications'.
Why are satellite dishes white and not mirrored?
Well, the satellite dishes in my area are mostly grey, not white - but to the question - why painted and not mirrored?. The wavelengths that need reflecting by the parabolic mirror of the satellite dish are in the microwave range - a millimetre or so. So, the dish need only be smooth compared to that length, and a paint finish meets that standard, though of course, most of the reflection is done by the metal of the dish. The paint need not be radio-conductive or radio-reflective. Were the dish needed to operate in the optical range, then indeed, a mirror finish would be needed.
The best material for satellite dish?
A satellite dish is just a reflecting surface to microwaves. As such, it has to be smooth compared to the wavelength of the microwave wavelength concerned. So any metal, (conducting surface) or even a metalized surface is OK. Otherwise it has to suit the manufacturing processes, and be suitable tor the physical environment in which it is erected. e.g. corrosion resistance, or snow and ice loading.
What is a clock glass?
a small dish
What is a sateliette?
A sateliette is a huge metal dish roatating the earths atmostphere. At a slow rate. We use the Sateliette's for our electrical needs such as TV Internet and other such things but we also use them for telophones using the same high frequency as another mobile phone :) Confusing stuff ah ?

How does the lunar rover vehicle looks like?
A lunar rover looks kinda like a 3X4 foot driving solar panel. It usually has a satellite dish connected to it for communication to NASA or something :D
Can you put warm mince in fridge?
yes you can, but you have to put on either a glass dish or metal dish
Microwaves will not pass through this?
Microwaves can cook any food in a dish unless the dish is made out of some kind of metal. The rays that a microwave produce can not penetrate anything that is metal.

Space satelites rely on this type of energy?
There's only one: -- In a receiving dish, the collected and focused electromagnetic energy changes to electrical energy in the feed, LNA, or LNB at the focus of the dish. -- In a transmitting dish, the electrical energy from the transmitter changes to electromagnetic energy, either at the focus of the dish if the transmitter is mounted there, or else some distance from the dish and then moved to the focus through a hollow 'waveguide'.
What three things would you see when a small piece of sodium metal is placed in a large dish of water?
1. Sodium metal whizzes and darts around the sides of the dish 2. Sodium metal gets smaller with time 3. A gas is evolved and the sodium metal may 'catch fire'
What Is a flat round portable metal disc with a plastic coating?
optical dish
How do you remove egg stains from metal or plastic?
you need just dish soap and water
When a metal powder is heated in open dish it turns black which metal is that?
The metal might be copper. When copper is heated, it reacts with oxygen in air forming copper oxide which is black in colour.
