Precise knowledge of the molecular polarizability is essential for designing experiments with ultracold molecules as lifetimes and lattice depths are key parameters. Specifically the wavelength at is of interest, since here, ultrastable high power lasers are available....
The effective area of an antenna in any specified direction is equal to the square of the wavelength multiplied by the power gain (or directive gain) in that direction, divided by 4π. effective bandwidth For a bandpass filter, the width of an assumed rectangular bandpass filter having the sa...
Here, the wavelength number k represents the spatial frequency and is measured in radians per metre. If the wave has more than one spatial dimension, then the wavenumbers are vector quantities. If the periodic waves are in non dispersive media, then the frequency will have an inverse relationshi...

in which λ is wavelength, k is constant, a = 2, and b = 3, 4, 5, … This group of lines was called the Balmer series. For the red line b = 3, for the green line b = 4, and for the blue line b = 5. Similar series were further discovered: in the infrared region, the...
SM Anderson,J Morton,K Mauersberger - 《Journal of Chemical Physics》 被引量: 88发表: 1990年 The Schumann-Runge absorption bands of 16O 18O in the wavelength region 175-205 nm and spectroscopic constants of isotopic oxygen molecules High-resolution absorption spectra of 16O 18O have...
The transition is not reported in the literature and detailed spectral analysis has been conducted to extract the molecular constants of the intermediate state. By carefully choosing the intermediate ro-vibrational state, the ionisation laser wavelength and controlling the excitation laser pulse energy, ...
Period, in physics, the interval of time it takes for a motion to repeat. Such motion is called periodic motion and is performed, for example, by a rocking chair, a bouncing ball, a vibrating tuning fork, a swing in motion, Earth in its orbit around the
in fact, a body emits radiation at all wavelengths. The energy radiated at different wavelengths is a maximum at a wavelength that depends on the temperature of the body; the hotter the body, the shorter the wavelength for maximum radiation. Attempts to calculate the energy distribution for the...
