The relationship between wavelength and period in confused seas, specified by a two-dimensional wave spectrum, has been investigated numerically for different wave spectra, directional spread parameters, and truncation or cutoff frequencies. The relationship was found to be sensitive to variations in the...
YuPhysical Oceanography Laboratory, Ocean University of Qingdao, Qingdao 266003, People’s Republic of ChinaReceived 26 October 1998; accepted 15 January 1999AbstractRelationships between the mean wavelength and mean wave-period of wind waves are derived for fetch-limited and fully developed seas.The ...
FIG. 8 is a complete output transmission curve for two of the four outputs of 1×4 PINC couplers such as those illustrated in FIG. 4(b); and FIG. 9 is a plot illustrating the relationship between the four PINC coupler output curves and the corresponding wavelengths of the preferred embodim...
This extremely simple relationship can be considered as the completely adequate expression of Wien's energy distribution law; for with the dependence upon the energy, the dependence upon the wavelength is always directly given through the general, well-established displacement law by Wien. Max Planck...
It can be seen that the secondary modulation BSs are composed of multi-period pulses. Then carefully adjusting the PC1 and PC2, the second-order BSs can be recovered as shown in Fig. 8(a2–a4). Consistent with the previous conclusion, BSs with π phase also have high stability and ...
with the wave vector, the magnitude of which is the wavenumber k, and the angular frequency ω. The wavenumber determines the wavelength, defined as the spatial period of the wave (e.g., the distance between subsequent oscillation maxima, see Figure 1):λ...
signal has a peak resulting from a sudden signal change within a comparatively short amount of time. On the other hand, a voltage component resulting from the opto-galvanic signal has a peak delayed by a predetermined period following the occurrence of the peak of the photoelectric effect signal...
Because the Bragg wavelength is directly proportional to the grating period a shift in the Bragg wavelength will be observed making possible to monitor the induced strain (Othonos, 1997). The sensitivities for strain and temperature of a FBG recorded at 1550 nm are approximately 1.2 pm με−...
The bit rate is simply the inverse of this period. These signals have an equivalent representation in the frequency domain, where the energy of the signal is spread across a set of frequencies. This representation is called the power spectrum, or simply spectrum. The signal bandwidth is a ...
Practice Problem #1 A wave in a spring has a wavelength of 0.1 meters and a period of 0.2 seconds. What is the speed of the wave? Practice Problem #2 Find the wavelength of a wave in a rope that has a frequency of 2.0 Hz and a speed of 0.4 meters/second....
