MCQ
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.
  • ✓
    De $–$ Broglie concluded that wavelengths of matter waves can be quantized.
✓

Answer

Correct option: D.
De $–$ Broglie concluded that wavelengths of matter waves can be quantized.

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.
