Q1 · Atoms · MEDIUM
The energy of an electron in the third orbit of a hydrogen atom is –1.51 eV. If the electron jumps from the fourth orbit to the second orbit, the wavelength of the emitted photon is approximately (Use: hc = 1240 eV·nm)
Q2 · Atoms · HARD
In hydrogen atom, the ratio of the frequency of radiation emitted when the electron jumps from n = 3 to n = 1 to the frequency when it jumps from n = 2 to n = 1 is
