A microwave oven or simply microwave is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. [1] This induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating .
The sulfur lamp consists of a golf ball-sized (30 mm) fused-quartz bulb containing several milligrams of sulfur powder and argon gas at the end of a thin glass spindle. The bulb is enclosed in a microwave-resonant wire-mesh cage. A magnetron, much like the ones in home microwave ovens, bombards the bulb, via a waveguide, with 2.45 GHz microwaves.
In the internal core form (see diagram), a glass tube (B) protrudes bulb-ward from the bottom of the discharge vessel (A), forming a re-entrant cavity. This tube contains an antenna called a power coupler, which consists of a coil wound over a cylindrical ferrite core. The coil and ferrite form the inductor that couples the energy into the lamp ...
The first commercial plasma lamp was an ultraviolet curing lamp with a bulb filled with argon and mercury vapor developed by Fusion UV. That lamp led Fusion Lighting to the development of the sulfur lamp, a bulb filled with argon and sulfur that is bombarded with microwaves through a hollow waveguide. The bulb had to be spun rapidly to prevent ...
The U.S. Food and Drug Administration (FDA) now classifies eggs as a “healthy, nutrient-dense" food, according to a new proposed rule. Registered dietitians react to the change.
Samsung then asked the uploader to sign a legal document requiring him to remove the video, remain silent about the agreement, and surrender any future claims against the company to receive a replacement. No further response from Samsung was received afterwards. [245] [246] There were a few more reported Galaxy S4 explosions in India [247] and ...
