It is possible that a muon be captured by a proton to form a muonic atom. A muon is identic to an electron, except when your mass, which is m = 105.7 MeV/c^2. What ia the smallest wave length for a Lyman series for this atom? Give your answer in pm.
Protons are accelerated from rest by a potential difference of 3.80 kVkV and strike a metal target. A) If a proton produces one photon on impact, what is the minimum wavelength of the resulting xx rays? Express your answer in meters.   B) Find the minimum wavelength if 3.80 −keV−keV electrons are used instead? Express your answer in meters.
A HeNe laser generates laser light with an output of 2.00mW and a wavelength of 632.8nm. a) how many photons do the larsen leave every second? b) if the laser beam illuminates an aluminum surface for one minute, which is the maximum number of electrons that can be released during that minute. c) what wavelength would the laser light need to have in order for the shortest de Broglie wavelength of the released electrons to be 548 pm d) if light with the wavelength you calculated in problem c) would illuminate a golden white instead, would you then expect released electrons with a shorter de Broglie wavelength than that in problem c)?
