Question

How did de – Broglie conclude the modification of Bohr’s II postulate?

(a) de – Broglie concluded that electrons cannot be quantized

(b) de – Broglie concluded that the wavelength of electrons should be reduced

(c) de – Broglie concluded that angular momentum cannot be quantized

(d) de – Broglie concluded that wavelengths of matter waves can be quantized

I got this question in an interview.

I need to ask this question from DE Broglie’s Explanation of Bohr’s Second Postulate of Quantisation in section Atoms of Physics – Class 12

Answer 1

The correct choice is (d) de – Broglie concluded that wavelengths of matter waves can be quantized

Explanation: de – Broglie concluded his modification of Bohr’s second postulate by stating that the wavelengths of matter waves can be quantized. This implies that the electrons can exist in those orbits which had a complete set of several wavelengths.
