reception. The optimal antenna size is one-half or one-quarter of a wavelength, so an audio frequency of 3000 Hz needs a wavelength of 100 km and a 25-kilometer antenna. Instead, with an FM carrier of 100 MHz with a wavelength of 3 meters, the antenna only needs to be 80 cm long....
Laser safety is an important topic. Everybody working with lasers has to follow the long-established occupational safety rules to prevent people from eye damage by accidental irradiation. These rules comprise, for example, the calculation of the Maximum
Chief among them is PVC. This kind of plastic (which can be identified by the 3 inside the recycling symbol these products bear) contains too many additives to be recycled in most cases, since these additives can affect the purity of a batch of recycled plastic. The remnants of the ...
