NEET Physics Bohr Model MCQ Question
Calculate the wavelength of the electron in the first orbit of the hydrogen atom according to de Broglie's hypothesis.
0.33 nm
0.53 nm
1.06 nm
2.12 nm
Correct Answer
Detailed Explanation
According to de Broglie's hypothesis, the wavelength λ of an electron is given by λ = h/mv. Using the given velocity of the electron v = 2.2 × 10^6 m/s and mass m = 9.1 × 10^-31 kg, we find λ = 6.63 × 10^-34 J·s / (9.1 × 10^-31 kg × 2.2 × 10^6 m/s) = 1.06 nm.
