Effect occurs as solar radiation is absorbed by the earth’s surface and re-radiated into the atmosphere, where it gets trapped and warms the earth.

Greenhouse effect

Explanation:

Green house effect can be defined as the effect that occurs due to the absorption of radiant energy that is trapped in certain molecules in the atmosphere.

The greenhouse gases trap heat and radiates it within the thermal infrared range. These gases are carbon dioxide, methane, nitrous oxide ozone and water vapors.

Due to this the average temperature of earth is adequate for living.

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
