Atomic StructureHard

Question

According to Maxwell’s theory of electrodynamics, an electron going in a circle should emit radiation of frequency equal to its frequency of revolution. What should be the wavelength of the radiation emitted by a hydrogen atom in the ground state if this rule is followed?

Options

A.4500 nm
B.450 nm
C.45 nm
D.4.5 nm

Solution

$\lambda = \frac{c}{v} = c.T_{n,z} = 3 \times 10^{8} \times 1.5 \times 10^{- 16} \times \frac{1^{3}}{1^{2}} = 4.5 \times 10^{- 8}\text{ m}$
