In the manufacture of PVC cellular plastic, a liquid plastic mixture is admixed with fibres in an amount of at most 0.050 percent by weight fibres, preferably carbon fibres having a length of about 1 cm, which fibres are distributed in the expanded cellular plastic isotropically with respect to both position and alignment. The cellular plastic is effective to dampen electromagnetic radiation within the radar range to at least 1-3 dB per cm.
These are sometimes called stealth aircraft.

inclined plainA ramp is an example of an inclined plane(:A ramp is an inclined planeincline planeA ramp belongs under the simple machine category of inclined planes. Inclined planes are sloping or slanting in figure which allows less effort to be exerted or applied, making work easier. The ramp has one end raised up to help raise an object, rather pushing a certain object than lifting it. Other examples of inclined planes other than the ramp are the stairs. When two inclined planes are put back to back, another simple machine called the wedge.
it's a screw because it is sort of a wedge and it has very thin inclined planes swirled around it.
Not easily, and frankly with today's periscopes, it's almost impossible; you'd have better luck spotting it visually. All modern submarine masts on submarines used by most navies are coated with radar absorption materials specifically to avoid being detected by radar of any kind.
meteorologists use a special kind of radar which is based on the?
Usually Doppler radar is used.
Radio waves.
No it did not because that kind of technology was not invented until WWII. At that time period when the Titanic was sailing it was not equipped with a radar.
