In physics, a laser is a device that emits light through a specific mechanism for which the term laser is an acronym: Light Amplification by Stimulated Emission of Radiation. This is a combined quantum-mechanical and thermodynamical process discussed in more detail below. As a light source, a laser can have various properties, depending on the purpose for which it is designed and calibrated. A typical laser emits light in a narrow, low-divergence beam and with a well-defined wavelength (corresponding to a particular color if the laser is operating in the visible spectrum). This is in contrast to a light source such as the incandescent light bulb, which emits into a large solid angle and over a wide spectrum of wavelength. These properties can be summarized in the term coherence.
That can burn you out dude...
A flashlight, electric torch or simply torch is a hand-held portable electric spotlight. It is known as a flashlight mainly in the United States and Canada and as a torch or electric torch in most Commonwealth countries.A typical flashlight consists of a small incandescent lightbulb with associated parabolic reflector, powered by electric batteries, and with an electric power switch. The components are mounted in a housing that contains the necessary electric circuit and provides ease of handling, a means of access to the batteries for replacement, and a clear covering over the lightbulb for its protection.Although a relatively simple device, its invention did not occur until the late 19th century because it depended upon the earlier invention of the electric battery and incandescent light bulb.
US Congress is working on legislation to phase out the incandescent light bulb.
The Green Focus crew head out to get rid of some incandescent light bulbs to make more room on the shelves for CFLs.
