What is the de Broglie wavelength associated to an electron of an hydrogen atom that is in the second exited state?

Use de Broglie's hypothesis to determine the speed of the electron in a hydrogen atom when in the n = 3 orbit, whose radius is 4.8x10-10 m. Three de Broglie wavelengths should fit around the n = 3 orbit. Express your answer with the appropriate units.

What is the frequency of light emitted from a hydrogen atom that makes a transition from the the n = 7 state to the n= 2 state (in Hz)?

Font Paragraph Styles Voice Sensitivity 5. The dispersion relation for propagating waves is the equation w = w(k) giving the angular frequency as a function of the wavenumber. A free-electron will have the energy-momentum relation E = 2m Use this relation, in conjunction with Planck's equation and De Broglie's equation, to determine the quantum mechanical dispersion relation for the wave associated with a free electron.

What is the wavelength of the radiation absorbed when an electron move from n = 2 to n = 5 for a helium +1 ion?

The energy of an electron in the first energy level of a certain atom is 9.6 eV. What is the wavelength of the electron at this level?

Use the Balmer's equation to Calculate wavelengths for transitions starting with states n; = 3 and 4, nf = 2 ending. What part of the electromagnetic spectrum do these wavelengths belong to? Where Rydberg's constant is R = 1.097x107 m².
