Radiation of the discharge plasma from a nanosecond breakdown in a nonuniform electric field of short interelectrode gaps is investigated. Voltage pulses with incident wave amplitude of ~10kV, pulse duration of ~1ns (FWHM), and pulse front duration of ~0.2ns are used. It is demonstrated that...
A method enabling the frequency of the radiation emitted by a multi-frequency CO2 laser to be determined with precision by adjusting the optical length of the resonant cavity, so as to be a multiple of the wavelengths of the two beams emitted, and so as to obtain a central dip in the po...

The role of UV radiation-induced photoproducts in initiating base substitution mutations in human cells was examined by measuring photoproduct frequency distributions and mutations in a supF tRNA gene on a shuttle vector plasmid transfected into DNA repair-deficient cells (xeroderma pigmentosum, complement...
Orthogonal frequency ultrasound vibration (OFUV) pulses are developed to generate ultrasound radiation force for stimulating vibrations in a tissue region with preferred spectral distribution. So we can increase specific vibration harmonics in which...
This chapter reviews the group frequencies in terms of the spectral regions in which they occur. The first part of the chapter outlines an orderly procedure for the initial interpretation of an unknown infrared radiation (IR) spectrum by regions. Then, spectra-structure correlations are shown in ...
Vibrational frequency refers to the characteristic modes of vibration exhibited by molecules, such as A1, A2, E, and E' in different geometries, as depicted in figures. These frequencies show periodicity with each vibration mode in AH3 molecules. ...
What is the frequency of ultraviolet light that has a wavelength of 338.3 nm? What is the wavelength of ultraviolet rays of 3.0 \times 10^{15} Hz frequency? (a) What is the frequency of a photon of UV radiation (\lambda = 2.00 \times ...
Germanium-doped silica fibers were prepared for frequency doubling of 1.06-microm wavelength radiation under the simultaneous presence of the first, second, and fourth harmonics of the laser light. It was found that the preparation rate for frequency doubling was dramatically increased by the presence...
