An electron traveling at 3.00 x 104 m/s is further accelerated to an excited state by a potential difference so as to reduce its de Broglie wavelength to one-third of its original value.
(a) How much voltage is required to accomplish this? The electron stayed in the excited state (Eexcited = 1.80 eV) 2.00 μs before moving to the ground state.
Find (b) the frequency and (c) the wavelength of the emitted photon.
(d) Find the approximate uncertainty in energy of the photon.
