Question

Plasma near a black hole moves at immense speeds. Most of this plasma is hydrogen, which emits a wavelength of light in the red at 6563 Angstroms (6.563x10-10 m). If we detect it at a wavelength of 6,456.4 Ang, how fast is the plasma moving as a fraction of speed of light? (Hint - use the doppler formula...a negative value would imply the plasma is moving towards us, while a positive would be away from us).
