A deuteron and an alpha particle are accelerated with the same accelerating potential. Which one of the two has
(1) greater value of de-Broglie wavelength, associated with it, and
(2) less kinetic energy? Explain.
Scientists observe a distant galaxy with a spectrometer. They find that the wavelength of the Lymann alpha Hydrogen line in the stars spectrum has shifted from its laboratory value of 121.6 nm to three times that value, 364.8 nm. According to the doppler effect, how fast is the galaxy receeding from us? (Find v/c of the galaxy relative to us).
