g If you have a light in your house on a dimmer switch you should try this yourself. In the space below write a paragraph about how the light from an incandescent source changes as the temperature decreases. Notice changes in both how bright the light is and what colors/wavelengths of light you can see. If you have such a light at your house you can also describe how the color and intensity of the light changes when you are just looking with your eyes and not through the spectrometer.

i don’t know what the answer is i wish i

ok

explanation:

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
