Question

In a laboratory, light from a particular spectrum line of
helium passes through a diffraction grating and the second-order maximum
is at 18.9 from the center of the central bright fringe. The same
grating is then used for light from a distant galaxy that is moving away
from the earth with a speed of 2.65 * 10^7 m>s. For the light from the
galaxy, what is the angular location of the second-order maximum for
the same spectral line as was observed in the lab?
