The de-Broglie wavelength of the electron in the first Bohr orbit of the hydrogen atom is
- A equal to the diameter of the first orbit
- B equal to the circumference of the first orbit
- C equal to the half circumference of the first orbit
- D independent of the size of the first orbit
Answer & Solution
Correct Answer
(B) equal to the circumference of the first orbit
Step-by-step Solution
Detailed explanation
According to de-Broglie hypothesis, revolving electron in circular orbit shows wave nature. Hence, a circular orbit can be taken to be a stationary energy state only if it contains an integral number of de-Broglie wavelength, i.e. we must have, \(2 \pi r_n=n \lambda\) where,…
