Given that the speed of light is 2.998 x 108 m/s, what is the frequency of a wave that has a wavelength of 3.55 x 10-8 meters? If the speed of light is 2.998 \times 10^8 m/s, what is the frequency of radiation w...
whereEmaxis the maximum possible energy,hthePlanck's constant,νmaxthe photon frequency, e the charge of the electron, andVthe acceleration potential. If the frequency is substituted with the wavelength, the above expression becomes hνmax=hc/λmin=eVandλmin=hc/eV=12398/V ...
Using direct solids analysis it was possible to perform S speciation with high analytical frequency, simplicity and precision. The intensities ratio for the different electronic transitions (S K alpha(1,2), S K beta and S K beta') and principal component analysis (PCA) of the spectra obtained...
The wavelength range of X-ray imaging is() A.0.031 ～ 0.008nm B.0.0006 ～ 50nm C.0.0008 ～ 50nm D.0.031 ～ 50nm 查看答案
A new method is described for measuring the wavelength of peak intensity of x-ray tubes. This method employs known absorption data and gives an independent check on crystal spectrometer measurements. For a tungsten target tube, the measured values were: 50.0 kv spectrum peak at 0.337 A, 45.5 ...
(b) Sketched microwave-to-magnon transduction: the resonant spin-precessional motion in disks (large arrows) is exploited to excite short-wavelength spin waves (small arrows highlighted by the oval) in YIG. Depending on the frequency, different wave vectors k1+nG (n=1, 2, 3, …) are ...
