Question 49

A proton of wavelength \(\lambda_o\) is emitted when an electron in an atom makes a transition from a level of energy 2E. If the electron transits from \(\frac{4}{3}E_k\) to E level, determine the wavelength of the photon that would be emitted

  • A.3\(\lambda_o\)
  • B.2\(\lambda_o\)
  • C.\(\frac{3}{4}\)\(\lambda_o\)
  • D.\(\frac{1}{3}\)\(\lambda_o\)
