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 ground state if this rule is followed?

Step-by-Step Verified Solution

**Answer:** Wavelength = 45.7 nm. **Step-by-Step Explanation:** According to Maxwell's theory, the frequency of radiation equals the frequency of revolution. For ground state: f = v/(2�r) = 2.18 _ 10_ / (2� _ 0.53 _ 10___) = 6.55 _ 10__ Hz. _ = c/f = 3 _ 10_ / (6.55 _ 10__) = 4.58 _ 10__ m = 45.8 nm � 45.7 nm [citation:14].
