NEET Physics Bohr Model MCQ Question
Consider a diagram depicting an electron in the fourth orbit (n=4) of a hydrogen atom according to the Bohr model. Which of the following conditions must hold true for the electron's orbit to be stable?
The circumference of the orbit equals four de Broglie wavelengths.
The orbit contains exactly three de Broglie wavelengths.
The circumference of the orbit equals two de Broglie wavelengths.
The orbit contains exactly five de Broglie wavelengths.
Correct Answer
Detailed Explanation
According to the de Broglie hypothesis integrated into Bohr's model, the electron's orbit is stable when its circumference is an integer multiple of the electron's wavelength, specifically four wavelengths for the fourth orbit.
