What is the number of photons of light with wavelength 4000 pm which provide 1 Joule of energy ?

The electron energy in hydrogen atom is given by En=(−2.18×10^−8)/n2J. Calculate the energy required to remove an electron completely from the n=2 orbit. What is the longest wavelength of light in cm that can be used to cause this transition? What is the number of photons of light with wavelength 4000 pm which provide 1 [...]

What is the energy in joules required to shift the electron of the hydrogen atom from the first Bohr orbit to the fifth Bohr orbit ? And what is the wavelength of the light emitted when the electron returns to the ground state ? The ground state electron energy is −218×10^−11 erg. What is the [...]

What is the wavelength of light emitted when the electron in a hydrogen atom undergoes transition from an energy level with n = 4 to an energy level with n = 2? What is the colour corresponding to this wavelength ? What is the number of photons of light with wavelength 4000 pm which provide [...]
