Oct 17, 2014 · The energy of light is related to its frequency and velocity as follows: E = hν = hC/λ. where E = energy. h = Planck's constant, 6.62517 x 10-27 erg.sec ν = frequency. C = velocity of light = 2.99793 x 1010 cm/sec λ = wavelength. The velocity of light, C, in a vacuum is 2.99793 x 1010cm/sec. Light cannot travel faster than this, but if it ...

In order to understand the physical properties, design, and fabrication of any display Abstract: technology, it is essential to have a good appreciation of the basic physics involved in the light sources and materials used in their construction. This does not mean that to be a display engineer you need an in-depth knowledge of Maxwell’s equations, ...
Light is a very complex notion which stems from the general properties of electromagnetic radiation. However, to use light in applications such as displays, it is often only the simplest concepts of propagation that are required. The basic theory of light propagation stems from complicated mathematical theories such as Maxwell’s equations [1] which...
Optical coherence is difficult to define as there are many types and unusual definitions. If we assume that light has a basic wave property as described above, then we are assuming that light is fully coherent. Unfortunately such light sources are very rare and even the highest quality laser light source will have some degree of unpredictability. T...
The job of the optical component design engineer is to marry together many different specifications along with the packaging and environmental specifications in order to create a commercially cost-effective component. Two very important considerations are the choice of materials used to make the waveguide and the fabrication methods employed. Radio...
Some crystals such as sodium chloride have a cubic molecular structure. When light passes through these structures it sees no preferred direction and is relatively unaffected. If the crystal has a structure such as hexagonal or triagonal, different directions of light will see very different crystalline structures. This effect is called birefringen...
A display engineer does not need an in-depth knowledge of Maxwell’s equations, but rather to understand the fundamental physical properties of light that lead to its control, propagation, and modulation. Key to this is an understanding of the basic wave properties of light and how this leads to an energy transfer, and properties such as polarizatio...
Following are the important properties of light –. Light travels in a straight line. The speed of light is faster than sound. Light travels at a speed of 3 x 10 8 m/s. Reflection of light. Reflection is the phenomenon in which light travelling in one medium, incident on the surface of another returns to the first medium, obeying the laws of ...

The properties of light are parameterized in similar ways in both the classical (wave) and semiclassical (photon) pictures of light. The fundamental physical properties of an electromagnetic wave are its wavelength λ, frequency ν and polarization state; alternatively, the first two of these properties may be stated in the form of a wave number k = 2πλ and angular frequency ω = 2πν.
