Question

Find out the wavelength of the electron orbiting in the ground state of hydrogen atom.

Answer 1

Radius of ground state of hydrogen atom
= 0.53 Å = 0.53 x 10^-10 m
According to de Brogile relation
2πr = nλ
For ground state n = 1
2 x 3.14 x 0.53 x 10^-10 = 1 x λ
∴ λ = 3.32 x 10^-10 m
       = 3.32 Å
