Question

Number of waves produced by an electron in one complete revolution in nth orbit

Answer 1

According to Bohr’s postulate of angular momentum, in the 3rd orbit

Mur = n h/2π

Mur = 3 (h/2π) …..(i) [n = 3]

According to de Broglie relationship

λ = h/mu ….(ii)

Substituting (ii) in (i), i get!

(h/λ) r = 3 (h/2π)

3λ = 2πr

Easy method!!

Number of waves = n(n - 1)/2

3(3 - 1)/2 = 3 * 2/2 = 3

Answer 2

Answer:

n

Explanation:

In general, in one complete revolution total waves produced will be equal to shell number.
