Light is an electromagnetic wave and travels at a speed of 3.00 × 108 m/s. the human eye is most sensitive to yellow-green light, which has a wavelength of 5.04 × 10-7 m. what is the frequency of this light?

Explanation:

As we know that the frequency of the wave is given as

here we know that

also we know that

now we have

the inner core.

good luck: )

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
