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

Answer

D

Explanation

Frequency of the revolution in the ground state `=(V_0)/(2pir_0)`
:. Frequency of radiation emitted is,
`(V_0)/(2pir_0)= f`
`lambda = (C2pir_0)/(V_0)`
`=(2 xx 3.142 xx 3 xx 10^8 xx 53 xx 10^-12)/(2187)`
`=45.686 nm= 45.7 nm`
