Figure shown the electron energy level , referred to the ground state (the lowest possible energy) as zero , for five different isoleted atoms. Which atom can produce radiation of the shortest wavelength when atoms in the ground state are bombarded with electrons energy `W`?

Options

A. A
B. B
C. C
D. D

Answer

B

Explanation

From the graphs given , atom in graph `B` will absorb must of the energy `W` from the electron and re-radiate, in all directions, rediation of shortest wavelength when the atom returns to its ground state.
