Задача 40907.

In the observation of the hydrogen line (lambda = 0.434 m) in the emission spectrum of the nebula we found that it shifted and has a wavelength of 0.4460 micron. In what direction and at what speed this nebula is moving relative to the Earth? What is the "red shift" to this line of hydrogen?
