Question

'The number of waves made by a bohr electron in one complete revolution in 3rd orbit?'
I don't want the answer..... Can anyone please explain this question to me and tell me that does wave in this question mean spectral lines?Please give the formula to find the answer

Answer 1

Answer:

In general, the number of waves made by a Bohr electron in an orbit is equal to its quantum number. Thus the circumference of the 3rd orbit is equal to 3 times the wavelength of electron i.e. the electron makes three revolution around the 3rd orbit
