Text Solution

Verified by Experts

From solved example 1, velocity of electron moving around a proton in hydrogen atom in an orbit or radius `5.3 xx 10 ^(-11) m ` is is `2.2 xx 10^6 m//s`
` epsilon = (v )/(2 pi r ) = ( 2.2xx 10^6 ms^(-1))/( 2 pi ( 5.3 xx 10^(-11)m))= 6.6 xx 10^(15) Hz`
According to the classical electronmagnetic theory , the frequency of the electromagnetic waves emitted by the revolving electrons is equal to the frequnecy of its revolution around the nucleus thus the initial frequency of the light emitted is ` 6.6 xx 10^(15) hz`
