Which statement would be the best evidence that heat transfer through radiation has occurred and why? a) a pan gets hot on a stove. radiation requires molecule to molecule contact. b) on a windy day, you feel colder. this is because more heat is removed from your body. c) at several feet from a fire, you still feel the heat. heat is transferred through the air. d) an oven uses fans to heat up the food inside faster. radiation is the most efficient form of heat transfer.

C. At several feet from a fire, you still feel the heat. Heat is transferred through the air.

Explanation: Heat is felt several feet away from the fire. Heat is transferred via radiation. It can be likened to how heat from the sun gets to the earth via radiation.

heat transfer via Radiation does not require any form of contact between the source of the heat and the heated object.

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
