The de-Brogile wavelength of an electron moving in a circular orbit is λ.

Question

The de-Brogile wavelength of an electron moving in a circular orbit is $λ$ . The minimum radius of orbit is

Options:

A . λπ

B . λ2π

C . λ4π

D . λ3π

Answer: Option B
:
B
We know

2 π r = n λ

From minimum radius

n = 1

2 π r_{m i n} = λ

r_{m i n} = \frac{λ}{2 π}
