While the rippling amplitude varies appreciably, the rippling wavelength varies very little and can be estimated from simple mechanical considerations.
This is rather significant for practical engineering, as the incident wavelength varies over a wide range in practice.
De Boissieu, Stéphane Pailhès of the University of Lyon in France, and colleagues measured the energy of each type of phonon as its wavelength varied.
The PL spectra showed an unchanging emission peak at 443 nm as the excitation wavelength varied, which is very different from the previous reports.
In the experiments, the ratio of the significant wave height to the water depth has values of 0.08, 0.12, and 0.16, and the relative size of the cylinder with respect to the wavelength varies from 0.44 to 1.26.
When the illumination wavelength varies to 830, 940, 1064, and 1312 nm, D2 shows a similar photovoltaic response at V bg = 5 V (see Additional file 1: Figure S6 ).
An emisson-scan was captured, in which the emission spectrum of Nile Red was recorded for one excitation wavelength, and an excitation-emission-scan was captured, in which the detection range varied from 480 to 690 nm while the excitation wavelength varied from 470 to 670 nm using the white light laser.
The refractive indexes of as-deposited, and 400 and 600 °C annealed ZnO thin films decreased with the annealing temperature in the visible spectrum, and as function of wavelength, varied from 1.93 to 2.16, 1.89 to 2.09, and 1.77 to 1.96, respectively.
Figure 4 shows how the detected spot wavelength varies with background optical properties.
