Electrons flow very slowly through a circuit, yet it does not take a noticeably long time for a lamp to light up when you turn on a distant switch. How quickly a lamp lights up after an electrical switch is closed does not depend on the drift velocity of the conduction electrons, but depends on the speed at which the propagates through the circuit, which is about the speed of light.

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.
