What will be the number of waves formed by a Bohr electron in one complete revolution in its second orbit?

Options

  1. Athree
  2. BTwo
  3. COne
  4. DZero

Correct answer

B. Two

Step-by-step solution

Number of waves = Circumeference of orbit de - Broglie wavelength of electron But, = h m v So, = 2 r h = 2 n m v r but aligned m v r & = n h 2 = 2 h n h 2 m v r & =n aligned For second orbit, n=2 Number of waves =2
