  1. A 3-way bulb has two filaments, one brighter than the other. You cnanswitch
    on dim, bright, or bright+dim. The socket has an additional contact
    compatible with the additional contact on the 3-way bulb.

    go to a hardware store and compare the bulbs and if you can
    also the sockets

    The 3-way bulb has two base contacts -- one in the center like a regular
    bulb, and one is a ring around the edge. The socket has a matching
    contact in the center and one that's off center. You can screw an
    ordinary 1-filament bulb into a 3-way socket and it'll work fine except
    that it'll be on-on-off-off instead of dim-medium-bright-off.

    What is the difference between a 3-way bulb socket (found in floor lamps)
    and the ordinary incandescent bulb socket on the ceiling? I think they are
    the same size, ie u can stick an ordinary bulb in there and it would fit.
    But that's where the similarity ends. Can someone please tell me how it is
    constructed differently?
