To understand redshift and blueshift, first, you need to remember that visible light is a spectrum of color each with a different wavelength.According to NASA, violet has the shortest wavelength at around 380 nanometers, and red has the longest at around 700 nanometers. When an object (e.g...
Extending the conjugation (increasing the number of repeat units, n) lowers the energy E(n) of the electron transition in the purely donor-substituted series 1a-4a (bathochromic shift). This effect is superimposed in the push-pull series 1-4 (b-d) by the effect of the intramolecular ...

Assuming an average wavelength of 3,727.4 for the [O II] doublet, the redshift is 0.4340 (not corrected for galactic rotation). The two galaxies on the slit are separated by about 2.5 arc s and are not well resolved on the spectrogram, so it is not certain to which one the redshift...

Galaxies with stellar masses as high as roughly 1011 solar masses have been identified1–3 out to redshifts z of roughly 6, around 1 billion years after the Big Bang. It has been difficult to find massive galaxies at even earlier times, as the Balmer
space medium would cause the central wavelength of a spectral line to shift to the red or to the blue, de- pending on the dispersion characteristics of the space medium. Moreover, this shift should depend on the thickness of the medium, or the distance between the ...

Although the absorption band at 502 nm did not shift with increasing concentration of DR-13 in methanol, the absorption band for the ICPDRSS shifted 28 nm toward shorter wavelength due to the antiparallel geometry of the azochromophores. A broad luminescence was observed for ICPDRSS and shifted ...
Distortions of the observed cosmic microwave background provide a direct measurement of the microwave background temperature at redshifts from 0 to 1 (refs. 1,2). Some additional background temperature estimates exist at redshifts from 1.8 to 3.3 base
