frequency and wavelength are directly proportional relationship

This is one of their defining characteristics. They are all related by one important equation: Any electromagnetic wave's frequency multiplied by We can use this relationship to figure out the wavelength or frequency of any electromagnetic. The energy of a photon, however, is directly proportional to its frequency and inversely proportional to its wavelength. This relationship can be symbolized by. Frequency and wavelength are inversely proportional.

Figure 2 is designed to clarify some of the terminology used in reference to electromagnetic radiation. The image illustrates an electromagnetic wave that propagates, or travels, in a direction from upper left to lower right. This wave travels at the speed of light and is known as a transverse wave, in which the direction of wave energy lies at right angles to the direction of propagation. The wave in Figure 2 is generating both electric and magnetic oscillating fields that are oriented at degree angles with respect to each other and also to the direction of energy.

The distance between two successive peaks of the wave is equivalent to the wavelength of the radiation. The frequency of the radiation, however, is determined by the number of oscillations per second, which is usually measured in hertz, or cycles per second.

Interactive Java Tutorial Manipulate a three-dimensional electromagnetic wave to achieve a better understanding of frequency and wavelength.

An increase in frequency produces a proportional decrease in the wavelength of light, with a corresponding increase in the energy of the photons that comprise the light. Thus, the relationship between the wavelength of light and its frequency in inversely proportional and can be illustrated by a simple equation: Upon entering a new medium, such as glass or water, the speed and wavelength of light is reduced, although the frequency remains unaltered.

The energy of a photon, however, is directly proportional to its frequency and inversely proportional to its wavelength. This relationship can be symbolized by another simple equation: Thus, as frequency increases, the energy of emitted photons increases.

The reverse is also true. As the frequency of radiation decreases, there is a corresponding decrease in the energy of emitted photons.

Since the energy of photons depends upon the energy of source electrons, very high-frequency electromagnetic radiation, such as gamma rays, X-rays, and ultraviolet light, possess very short wavelengths and, therefore, a great deal of energy.

For example, in an ocean wave approaching shore, shown in the figure, the incoming wave undulates with a varying local wavelength that depends in part on the depth of the sea floor compared to the wave height. The analysis of the wave can be based upon comparison of the local wavelength with the local water depth. The figure at right shows an example. As the wave slows down, the wavelength gets shorter and the amplitude increases; after a place of maximum response, the short wavelength is associated with a high loss and the wave dies out.

The analysis of differential equations of such systems is often done approximately, using the WKB method also known as the Liouville—Green method. The method integrates phase through space using a local wavenumberwhich can be interpreted as indicating a "local wavelength" of the solution as a function of time and space. In addition, the method computes a slowly changing amplitude to satisfy other constraints of the equations or of the physical system, such as for conservation of energy in the wave.

Crystals[ edit ] A wave on a line of atoms can be interpreted according to a variety of wavelengths. Waves in crystalline solids are not continuous, because they are composed of vibrations of discrete particles arranged in a regular lattice. This produces aliasing because the same vibration can be considered to have a variety of different wavelengths, as shown in the figure. The range of wavelengths sufficient to provide a description of all possible waves in a crystalline medium corresponds to the wave vectors confined to the Brillouin zone.
