As the length of the transducer decreases, the sound column will act less and less like a single plane wave, and, in fact, it is now more appropriate to consider it an angular spectrum of plane waves. For a transducer with an aperture L, sound waves spread out over an angle ±Λ/L,...
PROBLEM TO BE SOLVED: To solve a problem that in a conventional light-emitting device which combines a light-emitting diode element with a fluorescent material, it is impossible to provide a light-emitting diode lamp fitting that has uniform emitted-light color or emitted-light intensity in any...
PROBLEM TO BE SOLVED: To manufacture a light emission component which generates a red fluorescent lamp to generating cool red electroluminscence and visible high-frequency short wave ultraviolet light, by irradiating first light rays on a luminescent substance of which electron energy level is easy ...
Presently laser light can be focussed to intensities of the order of [Math Processing Error]1023W/cm216 (corresponding electric field [Math Processing Error]∼1012V/cm), and in near future intensities are expected to increase by two orders of magnitude or more16 (the corresponding electric ...
[134]. Although, often the limited application area and relatively small record length of measurements make them not so useful for generalised studies. For that reason the use of numerical models is advised in order to extent offshore analysis [26,99]. Satellite data can also be utilised for...
When the hole is shrunk to a dimension com- parable with the wavelength, the light manifests its wave nature and demonstrates a diffracted pattern.1 If the radius of the hole is further decreased to r,,l, it is expected that when the light passes through this hole on a perfectly ...
Ne is the number density of electrons, and Lp is the length of plasma column. The electron density-length product determines the GDD value. A standard gas at 1 atm pressure and room temperature has the number density of electrons of 2.5 × 1019/cm3. The number density of electrons of ...
