Sound & Light (Physics): How are They Different? Power stations produce low-frequency radio waves. The EM wave transfers enough energy to remove (eject) one or more electrons from the atom. The swell of a wave in the ocean, and the subsequent dip that follows, is simply a vibration or oscillation of the water at the ocean's surface. You may not be fully aware of it but on a daily basis. Since these antennas are mounted on high towers, the power density of the waves on someone standing under such a tower is hundreds of times lesser than the recommended limits. A radio detects a different portion of the spectrum, and an x-ray machine uses yet another portion. An easy way to remember UV light's placement on the electromagnetic spectrum is to examine the ends of the visible light spectrum: Red is the light with the longest wavelength . The process is called ionization and the wave that is capable of doing it is called an ionizing wave. Bluetooth devices use higher wavelength radio waves that have lower energies. Mechanical waves are caused by a disturbance or vibration in matter, whether solid, gas, liquid, or plasma. These gases are released by human activity. Radio Waves. In physics, electromagnetic radiation ( EMR) consists of waves of the electromagnetic (EM) field, propagating through space, carrying electromagnetic radiant energy. An electron volt is the amount of kinetic energy needed to move an electron through one volt potential. Electromagnetic Spectrum.
