[george bekefialan h barrett] anatomy of an electromagnetic wave science mission directorateelectricity can be static, like the energy that can make your hair stand on end. magnetism can also be static, as it is in a refrigerator magnet. a changing magnetic field will induce a changing electric field and viceversathe two are linked. these changing fields form electromagnetic waves. electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. this means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space. in the 1860's and 1870's, a scottish scientist named james clerk maxwell developed a scientific theory to explain electromagnetic waves. he noticed that electrical fields and magnetic fields can couple together to form electromagnetic waves. he summarized this relationship between electricity and magnetism into what are now referred to as "maxwell's equations.quotheinrich hertz, a german physicist, applied maxwell's theories to the production and reception of radio wav see full list on science.nasa.gov light is made of discrete packets of energy called photons. photons carry momentum, have no mass, and travel at the speed of light. all light has both particlelike and wavelike properties. how an instrument is designed to sense the light influences which of these properties are observed. an instrument that diffracts light into a spectrum for analysis is an example of observing the wavelike property of light. the particlelike nature of light is observed by detectors used in digital camerasindividual photons liberate electrons that are used for the detection and storage of the image data. see full list on science.nasa.gov one of the physical properties of light is that it can be polarized. polarization is a measurement of the electromagnetic field's alignment. in the figure above, the electric field (in red) is vertically polarized. think of a throwing a frisbee at a picket fence. in one orientation it will pass through, in another it will be rejected. this is similar to how sunglasses are able to eliminate glare by absorbing the polarized portion of the light. see full list on science.nasa.gov the terms light, electromagnetic waves, and radiation all refer to the same physical phenomenon: electromagnetic energy. this energy can be described by frequency, wavelength, or energy. all three are related mathematically such that if you know one, you can calculate the other two. radio and microwaves are usually described in terms of frequency (hertz), infrared and visible light in terms of wavelength (meters), and xrays and gamma rays in terms of energy (electron volts). this is a scientific convention that allows the convenient use of units that have numbers that are neither too large nor too small. see full list on science.nasa.gov the number of crests that pass a given point within one second is described as the frequency of the wave. one waveor cycleper second is called a hertz (hz), after heinrich hertz who established the existence of radio waves. a wave with two cycles that pass a point in one second has a frequency of 2 hz. see full list on science.nasa.gov electromagnetic waves have crests and troughs similar to those of ocean waves. the distance between crests is the wavelength. the shortest wavelengths are just fractions of the size of an atom, while the longest wavelengths scientists currently study can be larger than the diameter of our planet! see full list on science.nasa.gov an electromagnetic wave can also be described in terms of its energyin units of measure called electron volts (ev). an electron volt is the amount of kinetic energy needed to move an electron through one volt potential. moving along the spectrum from long to short wavelengths, energy increases as the wavelength shortens. consider a jump rope with its ends being pulled up and down. more energy is needed to make the rope have more waves. top of page next: wave behaviors national aeronautics and space administration, science mission directorate.
