Explanation:

The wavelength is defined as

Where represents the wavelength, the speed of the wave which is a constant and is the frequency of the wave,

In this case, we know

, where

Replacing these given values in the formula, we have

But, we know that

So, we use the equivalence to transform the wavelength from meters to nanometers.

Therefore, the wavelength is 413.2 nanometers, approximately.

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
