The electromagnetic spectrum is separated into many categories and subcategories, based on the frequency and wavelength, source, and uses of the electromagnetic waves. Any electromagnetic wave produced by currents in wires is classified as a radio wave, the lowest frequency electromagnetic waves.
Electromagnetic waves span a spectrum that ranges from long wavelength, low frequency radio waves to short wavelength, high frequency gamma rays.
Explain why the higher the frequency, the shorter the wavelength of an electromagnetic wave. Draw a simplified electromagnetic spectrum, indicating the relative positions, frequencies, and spacing of the different types of radiation bands.
The following table gives approximate wavelengths, frequencies, and energies for selected regions of the electromagnetic spectrum. The notation "eV" stands for electron-volts, a common unit of energy measure in atomic physics. A graphical representation of the electromagnetic spectrum is shown in the figure below.
As seen in Figure 4, the blackbody curve has a peak at a given wavelength (or frequency), and this peak gets higher as the body’s temperature increases, meaning that the area below the curve also gets bigger.
5 Νοε 2013 · Listed below are the approximate wavelength, frequency, and energy limits. of the various regions of the electromagnetic spectrum.
28 Δεκ 2020 · Electromagnetic waves can come in many different wavelengths and different frequencies, so long as the product of the wavelength and frequency of a given wave equals the speed of light (that is, λf = c).
