The other person who answered is incorrect- the real answer is light.

Explanation:

A mechanical wave is a wave that requires a medium. A medium is any substance that has a defined set of physical properties and can transmit energy. A medium can be a solid, liquid, or gas. Some examples of a medium include an iron bar, the ground, water, lava, air, and helium in a balloon.

The answer is not sound because sound travels through waves through the air. If you were to put a source of sound in a container that contains no air, you would not be able to hear the sound through the container. Since sound has a wave and a medium, it is a mechanical wave.

The answer is not waves in the ocean because, obviously, this is a wave. Its medium is the water. Since it has a wave and a medium, it is a mechanical wave.

The answer is not waves in a wheat field because, again, this is a wave. The medium is the air. Since it has a wave and a medium, it is a mechanical wave.

The answer is light. Light travels through electromagnetic waves. However, it does not require a medium. Light can travel not only through air and solid materials, but also through the vacuum of space. Since light does not require a medium, it is not a mechanical wave.

I hope this helps !! :)

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
