   If one illuminates two parallel slits, the light from the two slits again interferes. Here the interference is a more pronounced pattern with a series of alternating light and dark bands. The width of the bands is a property of the frequency of the illuminating light. [20] (See the bottom photograph to the right.) Young's drawing of diffraction

6. Incandescent light bulb - Wikipedia

8. 3-way lamp - Wikipedia

   en.wikipedia.org/wiki/3-way_lamp

   A 3-way lamp, also known as a tri-light, is a lamp that uses a 3-way light bulb to produce three levels of light in a low-medium-high configuration. A 3-way lamp requires a 3-way bulb and socket, and a 3-way switch. In 3-way incandescent light bulbs, each of the filaments operates at full voltage. Lamp bulbs with dual carbon filaments were ...
