Protons are accelerated from rest across 480 V. They arethen directed at two slits 0.70 mm apart. How far apart willthe interference peaks be on a screen 28 m away?
Calculate the velocity of a star moving relative to the earth if you observe a wavelength of 91.0 nm for ionized hydrogen capturing an electron directly into the lowest orbital (that is, a ni = ∞ to nf = 1 , or a Lyman series transition).
A pulsar is a rapidly spinning remnant of a supernova. It rotates on its axis, sweeping hydrogen along with it so that hydrogen on one side moves toward us as fast as 50.0 km/s, while that on the other side moves away as fast as 50.0 km/s. This means that the EM radiation we receive will be Dopplershifted over a range of ±50.0 km/s . What range of wavelengths will we observe for the 91.20-nm line in the Lyman series of hydrogen?                  (Such line broadening is observed and actually provides part of the evidence for rapid rotation.)
