spectrum The range of electromagnetic radiation (electromagnetic waves) in our known universe, which includes visible light. The radio spectrum, which includes both licensed and unlicensed frequencies up to 300 GHz has been defined worldwide in three regions: Europe and Northern Asia (Region 1); North and South America (Region 2), and Southern Asia and Australia (Region 3).

3 where c is the speed of light, x 108 m/sec, f is the frequency in hertz (s1) and λ is the wavelength in meters (m). It is customary to report infrared spectra in terms of wavenumbers, which are relatively small, simple numbers equal to 1/ λ and typically given in units of cm1. These relationships are shown in Table 1.

Strip mining is the practice of mining a seam of mineral, by first removing a long strip of overlying soil and rock (the overburden); this activity is also referred to as overburden is most commonly used to mine coal and lignite (brown coal).Strip mining is only practical when the ore body to be excavated is relatively near the surface and/or is mostly horizontal.

With the development of IoT in smart cities, the electromagnetic environment (EME) in cities is becoming more and more complex. A full understanding of the characteristics of past spectrum resource utilization is the key to improving the efficiency of spectrum management. In order to explore the characteristics of spectrum utilization more comprehensively, this paper designs an EME portrait model.

mineral identifiion with an IR spectrum. However, the quality of the spectrum and its match with known mineral spectra will depend on the character of the sample. Large samples with good cleavages or flat crystal surfaces work best for the front reflection method. We will use the MHC FTIR reflection database to identify reflection spectra.

· The Electromagnetic Spectrum as a Probe of the Universe All objects in our Universe emit, reflect, and absorb electromagnetic radiation in their own distinctive ways. The way an object does this provides it special characteristics which scientists can use to probe an object s composition, temperature, density, age, motion, distance, and other chemical and physical characteristics.

In the early days of mining at Franklin NJ UV lights were an essential tool in loing the ore veins. Fluorescence is a "cold light" (luminescence) caused by electromagnetic radiation. There are many forms of electromagnetic radiation: visible light, radio, infrared, ultraviolet, Xrays, and gamma rays are all forms of electromagnetic radiation.
