Good electricity conductors can stop the radio waves in their tracks.
You should be able to receive a radio signal in a tank, made of steel, which is good conductor. Surely, tanks use radios for communication but the radio antenna sticks out for that reason, while for safety of the radio transmission should be much wiser to keep the antenna inside under cover.
Moreover, water (again good conductor) prevents submarines from receiving traditional radio waves. The very long waves can go through though, the Navy uses 76Hz frequency for example. For many reasons long waves are impractical to use.
That gives you in meters: 3947368.421052632m, nearly 4000 km!

What happens when light enters a glass block?
If the Glass Block acts as a Prism, then when you shine white light on a it, the White Light refracts into all Primary Colors. When the Light exits the Prism you can see all the rainbow colors.
What is the function of wooden block?
Wooden blocks used in science are used as weighing materials and converting measurements. Wooden blocks as children's toys are used to teach balance to kids.
Best material to make a house?
The materials needed to make a model house depends on what type of house you are making. Some model houses can be bought in kits and just need assembling while others require lots of materials. Materials can include cardboard, adhesive, twigs and even stones.
How do you use the word circulation in a sentence?
You must arrange the furniture so that it doesn't block the circulation of air conditioner.
How can I effectively block microwaves?
To effectively block microwaves, you can use materials that are dense and thick, such as metal sheets or mesh screens. These materials can reflect or absorb the microwaves, preventing them from passing through. Placing these materials around the area you want to protect can help block the microwaves effectively.
Can microwaves pass through any objects or do they easily get blocked?
Microwaves can pass through many materials, but their ability to penetrate objects depends on the material's composition and thickness. Dense materials like metal can block microwaves, while transparent materials like glass can allow them to pass through.
Does glass allow microwaves to pass through them?
Yes, glass is transparent to microwaves and allows them to pass through, which is why microwave ovens have glass doors. However, if the glass contains metal components, it may block the microwaves from passing through effectively.
What stops microwaves from penetrating certain materials?
Certain materials, like metals and thick metals, can block microwaves because they reflect the waves instead of letting them pass through. This is due to the properties of the material that prevent the microwaves from penetrating.
What can block microwaves from penetrating through objects?
Metal objects can block microwaves from penetrating through other objects.
What stop microwaves?
Materials such as metal, aluminum foil, and thick ceramics can block or reflect microwaves, preventing them from passing through and effectively stopping them. Additionally, microwave-safe containers made of glass or certain plastics are designed to allow microwaves to pass through them without being significantly affected.
What blocks infrared radiation from passing through?
Opaque materials, such as metals and certain types of glass, block infrared radiation from passing through. These materials absorb and reflect the infrared radiation, preventing it from transmitting through them.
Do microwaves pass through walls?
Yes, microwaves can pass through walls, but the ability to do so depends on the type of wall material and thickness. Certain materials like concrete and metal can block or reflect microwaves, while others like wood or drywall may allow them to pass through with some attenuation.
What stops radio waves from traveling through certain materials?
Certain materials, such as metals and thick concrete, can block radio waves from traveling through them because these materials absorb or reflect the waves, preventing them from passing through.
How can I effectively block microwaves from interfering with my electronic devices?
To effectively block microwaves from interfering with electronic devices, you can use materials that absorb or reflect microwaves, such as metal foils, metal mesh screens, or specialized shielding materials. Placing your electronic devices in a shielded enclosure or using a Faraday cage can also help block microwave interference.
How can mirco waves be blocked?
Yes, microwave waves can be blocked. A Farady cage is one way to block microwave waves, or you can use aluminum foil to block the waves. Most do not believe that microwave waves are that harmful and therefore do not need to be blocked.
How do opaque materials let light through them?
Opaque materials do not let light pass through them; they block or absorb light instead. This is because the atoms and molecules in opaque materials are closely packed together, preventing light from passing through the material.
