How much depth will radio waves penetrate in a wrinkled aluminium foil ball?
How much will radio waves penetrate an aluminium foil ball to tell us what is inside of it?
Can aluminum foil protect against radiation? 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? Why does aluminum foil improve antenna reception? What is the difference between tin foil and aluminum? Can you put aluminium foil in direct contact with food? Are aluminium foils safe for use with the air fryer? What are the properties of radio waves? Could we use 13cm wavelength radio waves to see a message in a paper? How is the density of an aluminum metal determined? What is the process to determine the density of aluminum and how does tin compare? Which material is less (time) durable: aluminium or plastic foil? Is aluminum a pure substance? How do radio waves work in space? Could we use radio waves and microwaves (with enough small wavelength) to read a message in a wrinkled paper, metal or a rock? How is the density of aluminum determined? Which side of the aluminum foil should I have facing out when cooking? How are radio waves emitted? 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? Is it safe to use aluminum pans or aluminum foil? Could we use arecibo radar frequencies to read a message in a paper in an alluminium ball buried in a planet? What are radio waves? How do we convert electrical energy into radio waves? What is the process to determine the density of aluminum and how does brass compare? How do radio waves travel? Can radiotelescopes as arecibo image the subsurface of an asteroid or a planet penetrating into atmosphere and surface: several cm of metal or rock? Could we use a radio waves of 100 or 1 meter wavelength to read a message written in a paper? Is it safe to bake with aluminum foil? Does aluminum conduct electricity?
