- Tech Please don't provide the handwriting solution A ground state hydrogen atom absorbs a photon of light having a wavelength of 92.05nm. It then gives off a photon having a wavelength of 901.3nm. What is the final state of the hydrogen atom? Values for physical constants can be found in the Chempendix. n_(f)=Would the red beam or the blue beam Be better at dislodging electrons from a metal surface? Explain your answer."One atom with three energy levels" breifly explain the roles of spontaneous and stimulated emission in the amplification of light in the optical cavity. Make it clear why both are important.
- 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.
