Question

Calculate the wavelength of an electron in the first orbit of hydrogen ?

Answer 1

Answer:

Calculate the de broglie wavelength for an electron in the first bohr orbit of a hydrogen atom

λ = the circumference (2πr) of orbit for n=1. That is, an electron in the first bohr orbit.

E = (-) ke² / 2r. For the ground state (n=1)

λ = 3.326^-10 m.
