Which of the following is/are correct.

Options

A. If quantum number is very large frequency of photon emitted when jumps from a orbit to next lower orbit is equal to the interger multiple of the frequency of revolution of electron in previous orbit
B. Electron debrogile wavelength depends on kinetic energy of elctron
C. Energy of elctrons is quantized in `Li^(++)` atom
D. Electrons cannot exists inside nucleus because they are altracted by protons inside nucleus

Answer

A, B, C

Explanation

Frequency of photon `= (me^(4)z^(2))/(8in_(0)^(2)h^(3))[(1)/((n-1)^(2)) - (1)/(n^(2))]`
Frequency of revolution of electron `= (me^(4)z^(2))/(4in_(0)^(2)h^(3)n^(3))`
