How much depth can radio waves penetrate in a wrinkled aluminium foil ball?
How much depth will radio waves penetrate in a wrinkled aluminium foil ball?
Can radar frequencies of 13 cm aprox be used to read a paper buried in an aluminium ball beneath the surface (of a planet for example)? Can radio waves and microwaves penetrate soil/rock/walls/metal? Can aluminum foil protect against radiation? Could we use radio waves and microwaves (with enough small wavelength) to read a message in a wrinkled paper, metal or a rock? Why does aluminum foil improve antenna reception? Could we use 13cm wavelength radio waves to see a message in a paper? Which material is less (time) durable: aluminium or plastic foil? Could sound waves leave traces in any surface or medium? Have low frequency X rays (close to Uv rays) or high frequency Uv rays (close to x rays) enough small wavelength to penetrate rock/soil/wall/aluminium? Could we see a 0.5 millimeter little stone with a 13 cm wavelength radio wave? Can radio waves be converted into electrical waves? What are the properties of radio waves? What is the difference between tin foil and aluminum? How do radio waves work in space? If radiowaves are reflected from objects (i.e planets) and they can penetrate a bit in the surface, we could image the subsurface isn't it? If radiowaves are reflected from objects (i.e planets) and they can penetrate a bit in the surface, we could image the subsurface right? Can you put aluminium foil in direct contact with food? How do radio waves travel? Why are radio waves transverse? What is more (time) durable: plastic film or aluminium foil? How are radio waves emitted? What makes materials transparent? Why can't radio waves transmit through water? Could we use a radio waves of 100 or 1 meter wavelength to read a message written in a paper? Can radiotelescopes as arecibo image the subsurface of an asteroid or a planet penetrating into atmosphere and surface: several cm of metal or rock? Are aluminium foils safe for use with the air fryer? Do we need any medium to transport electromagnetic waves? Is it possible to fake telephone waves? Can electromagnetic waves be reflected? What are some of the dangers of radio waves?
