Which example best illustrates the transfer of energy between two waves? a) a buoy rises in the water as a boat speeds past. b) a basketball rebounds from the backboard during a missed shot. c) an egg that rolls off the counter falls and breaks on the floor. d) a car that rear ends another car causes damage to both vehicles.

Option A

Explanation: Waves (mechanical and electromagnetic) can transfer energy when they impact into something.

When a boat speeds in the water, the boat itself pushes water around it generating mechanical waves in the water, those mechanical waves now travel on the surface of the water. When those mechanical waves impact the buoy, the waves also move the buoy, and now the buy is in a "wave-like" motion (you can model the movement of the buoy as a mechanical wave, that goes up and down), so this is a good example of energy transfer.

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
