• WHY are the frequency of FM channels typically between 90 and 110 MHz?

The FM term is somewhat misleading, because it stands for frequency modulation, a technique of broadcasting radio waves. Frequencies between 80MHz to 110MHz, generally used for FM broadcast around the world, all fall into the frequency range of 30Mhz to VHP 300Mz. However, the first FM transmission has occurred in the U.S. in the 1940s in the frequency range 42 to 50MHz. Later, in 1945, the Federal Communications Commission has allocated 88 to 106MHz bands for broadcasting FM, citing its non-interference with other radio bands in and around the city later in Western Europe, due to the medium wave band already saturated, broadcasters prefer to migrate to the usual standard FM band. In the United Kingdom, the BBC has broadcast for the first time in the FM band in 1955. Since then, FM has almost become an international standard for local programs within the city and the range of frequencies used around the world have been around of 88-106 MHz only.

• How does a laser printer?

A laser printer uses the phenomenon of static electricity as a temporary glue. The core component is the photoreceptor, in general, a rotating drum or cylinder. This is made for materials that very photoconductor is'discharged by photons of light. The printer coats the drum with a "positively charged toner - a fine black powder. As a positive charge, the toner adheres to the negative discharged areas of the drum, but not to positive charge 'background'. With the powder pattern affixed, the drum rolls on a sheet of paper, which travels along a belt below. Before the paper rolls under the drum, it is given a negative charge by the corona wire transfer (fee roller). This charge is stronger than the load negative electrostatic image, so the paper can be drawn from the toner powder away. As it moves to the same speed as the drum, the document reproduces the image pattern exactly to keep the paper to cling to the drum, it is rejected by the corona wire immediately after picking DETAC up the toner cartridge.
