The H-alpha spectral line has a wavelength of 656 nm in the laboratory. Light of this wavelength is incident at a diffraction grating. The first order maximum is produced at an angle of 36.0^(° ) .The same spectral line from a receding star is observed with the same diffraction grating...
H-alpha light is emitted by hydrogen atoms, by far the most common element in the Sun, when electrons within those atoms absorb energy andrise to a higher energy levelor orbit. When they cascade back to their original orbits, they release that energy as crimson light with a wavelength of ...

The observed contrast profiles are compared with profiles calculated on the basis of...
The depths of the absorption lines provide information about temperature, and the wavelength shifts of the lines tell us the motion of gas. If the Sun consisted only of pure hydrogen, there would be no absorption line. This would mean that the researchers could not study the temperature or ...
The Fraunhofer lines are, indeed, a lifeline of solar physicists. The depths of the absorption lines provide information about temperature, and the wavelength shifts of the lines tell us the motion of gas. If the Sun consisted only of pure hydrogen, there would be no absorption line. This ...
For induction of expression the cultures were grown to a density yielding an optical density (OD) of 0.6 at a wavelength of 600 nanometers (OD600), then 0.4 mM IPTG was added to induce the T7 system. The cells were harvested about 90 minutes after induction. ...

We construct oscillation power spectra of the line intensity for different wavelength, and compare these with the corresponding height-dependent power spectra of atmospheric parameters from the simulations. We find correlations between the power spectra of intensities of the line profiles at certain ...
The bandgaps were acquired by Tauc plot as the following: (αhν)n = B(hν − Eg) where α is the absorbance at a wavelength λ; hν is pho- ton energy and is equal to hc/λ; c is speed of light; h is equal to 4.1356676969 × 10–15 eV‧s; B is a ...
