If ( a ₀ ) is denoted as the Bohr radius of hydrogen atom, then what is the de-Broglie wavelength (( ) ) of the electron present in the second orbit of hydrogen atom? [n : any integer]

Options

  1. A( 8 a₀ n )
  2. B( 2 a₀ n )
  3. C( 4 n a ₀ )
  4. D( 4 a₀ n )

Correct answer

A. ( 8 a₀ n )

Step-by-step solution

r_n= a₀ n^2 z Also, 2 r _ n = n Where is de-Broglie wavelength 2 a ₀ n ^2 z = n For second orbit of H -atom = 8 a ₀ n
