Answer to Question #62022 in Atomic and Nuclear Physics for sourav

Question #62022
1. a) Calculate the ionisation energy of rubidium per atom, if light of wavelength 5.84 x 10 raised to the power of -8 m produces electrons with a speed of 2.450 x 10 raised to the power of 6 m/sec.
[Hint: Assume that the threshold frequency refers to the frequency corresponding to the ionisation energy.]

b) Assume that the electron in Li raised to the power 2+ ion is in third orbit. Calculate
i) the radius of the orbit and,
ii) the total energy of the electron.

[Hint: Li raised to the power 2+ ion also has atomic spectra similar to hydrogen atom. While applying relevant equations, use Z = 3.]
