WebThe easiest way to locate long waves is using a 0 to 5-wave chart. However, if a 0 to 5-wave chart is unavailable, the standard means of identification is using the 200 to 300-mb charts. Satellite methods of identifying long waves may also be used. The main axis of the polar front jet tends to outline the current long-wave pattern. http://www.strobbe.eu/on7yd/136ant/ gray hair definition

At 300 °C to 750 °C the ceramic emitters emit medium to long wave IR-radiation between 2 and 10 µm. Most plastics and many other materials absorb this wave length range very well. Basically there are two types: Solid Ceramic Emitters and Hollow Ceramic Emitters.
