One of the emission lines of the hydrogen atom has a wavelength
of 93.07 nm. In what region of the electromagnetic spectrum is this
emission found? Determine the initial value of n associated with
this emission.
Emission lines from the hydrogen Hβ line (rest wavelength of
486.1 nm) are observed in the spectrum of a spiral galaxy at
redshift z = 0.9. The galaxy's disk is observed to be inclined at
an angle of 45 degrees to the line of sight. The central wavelength
of the line is observed to be shifted by 0.5 nm to the red on one
side of the galaxy, and by 0.5 nm to the blue on the other side of...
