JEE Main 2024 Chemistry question
Frequency of the de-Broglie wave of electron in Bohr's first orbit of hydrogen atom is × 10¹³ Hz. (nearest integer) [Given: (Rydberg constant) = 2.18 × 10⁻¹⁸ J, h (Planck constant) = 6.6 × 10⁻³⁴ J·s.]
Answer: 661
Solution
One de Broglie wavelength fits the first orbit, so the wave's frequency equals the orbital
