FIELD: electronic equipment.;SUBSTANCE: invention relates to methods for ensuring the durability of electronic onboard equipment. Essence of the invention lies in the fact that the method of estimating the frequency of single radiation effects, namely failures and failures, in the onboard equipment ...
The number of turns per second is the frequency of the light. Now take another path; it has, for instance, a different time, so the vector for it is turned through a different angle—the angle being always proportional to the time. Take all the available paths and add on a little ...

of atoms to higher energy levels by incident photons at the resonance frequency of the gas or vapor; the radiation is characteristic of the particular gas or vapor atom but is not necessarily the same frequency as the absorbed radiation. Also known as resonance fluorescence; resonance luminescence...
Optimization of laser output parameters vs. f-to-2f beating signals can be mutually contradicting, when an octave-spanning supercontinuum is employed for f-to-2f measurements. We show that resonant dispersive waves will solve this issue, thanks to their frequency stability against changes in laser ...
What is the frequency of a photon of ultraviolet radiation with a wavelength of 365nm?Ultraviolet Radiation:Ultraviolet radiation is one section of the electromagnetic spectrum. The range of wavelengths for ultraviolet radiation are between 400 nm - 10 nm. Ultraviolet radiation is di...
We report measurements of absorption of pulsed CO 2 laser radiation by SF 6 at 140 K. These measurements cover a broad range of fluence (10 6 to 0.8 J/cm 2), SF 6 gas density (2 × 10 15 to 6 × 10 16 cm 3), and frequency (six CO 2-laser frequencies within the SF 6 v ...
(b). Simulated results show that the input VSWR of the feeding network is below 1.5 over the frequency range from 28 to 31.8 GHz, the phase imbalance of output ports is less than 1.6 degree, and the power imbalance is about 0.3 dB. Then, the output signals of the dividers are shifted...
