Question

Consider an electron in the n th orbit of a hydrogen atom in the Bohr model. The circumference of the orbit can be expressed in terms of de Broglie wavelength λ of that electron as

(a) (0.529) nλ

(b) √nλ

(c) (13.6) λ

(d) n λ

Answer 1

The correct option is (d) n λ.

Explanation:

The circumference of an orbit in an atom in terms of wavelength of wave associated with electron is given by the relation, 

Circumference = nλ

where n = 1,2,3,...
