Examples of wavelength


wavelength
To determine the appropriate b for these experiments, we calculated growth factors for different wavelengths and matched them to the experimental data.
At laser wavelengths of the order of 1 mm, successful fast ignition requires strong anomalous laser beam-pellet coupling.
The structure of this 0.5-mm mode is highly periodic, implying a much narrower spectrum of wavelengths than in single wires z pinches.
The initial density profile shows a spectrum with larger amplitudes at longer wavelengths.
The main aspect concerns the possibility of extending the range of applicability to other absorption edge wavelengths, that is, other elements.
Moreover, the atmospheric and surface conditions necessary for such life are likely to provide only a limited spectral window of transmitted wavelengths of that light.
The purple bacteria, therefore, must ' make their living ' by utilizing green light and far-red light of wavelengths above 750 nm.
Specifically strong lines were found at wavelengths corresponding to energies of q x 13.6 where q = 1, 2, 3, 4, 6, 7, 8, 9, 11.
A second class is transformed to a solitary-wave solution where the spectrum at short wavelengths is more rapidly damped than at long wavelengths.
The perturbations were assumed to be of sufficiently short wavelengths to justify the slow time and radiusfrozen-in approximation for the unperturbed systems.
Accordingly, it is of practical interest to examine the wave spectra that span from long to short wavelengths.
The present study investigates this possibility, that some wavelengths are more susceptible.
With the exception of the enstatite, it seems that there are few specific features at wavelengths longer than y300 nm.
