Question
How did de – Broglie modify Bohr’s postulate?

Answer

  1. De – Broglie suggested that electrons behaved like a wave.
Explanation:
de – Broglie hypothesis did modify Bohr’s second postulate.
This postulate of Bohr regarding the quantization of the angular momentum of an electron was further explained by Louis de Broglie.
According to de – Broglie, a moving electron in its circular orbit behaves like a particle-wave.
