Question: The energy of the first excited state of a hydrogen
The energy of the first excited state of a hydrogen atom is –0.34eV ± 0.0003 eV. What is the minimum average lifetime for this state?
Answer to relevant QuestionsWhat is the minimum uncertainty in the speed of an electron that is known to be somewhere between 0.050 nm and 0.10 nm from a proton? What is the energy of the photons produced in proton–antiproton pair annihilation, assuming that both particles are essentially at rest initially? An electron microscope is an instrument that uses electrons instead of light for the imaging of objects. A mono-chromatic beam of electrons is accelerated through a potential difference of 50 V. What is the ratio of the ...A charged particle is accelerated through a potential difference V. If the voltage were doubled, what would be the ratio of the new de Broglie wavelength to the original value? Explain how the fusing of very light nuclei and the split-ting of very heavy nuclei can both release energy.
