Question:medium

De-Broglie wavelength of an electron orbiting in the \(n = 2\) state of hydrogen atom is close to (Given Bohr radius = 0.052 nm):

Show Hint

Remember Bohr's quantization condition \( 2 \pi r = n \lambda \), relating the circumference of the electron's orbit to its de Broglie wavelength. Also, recall the formula for the radius of the \(n^{th}\) Bohr orbit \( r_n = n^2 a_0 \).
