The number of revolutions made by electron in Bohr's 2nd orbit of hydrogen atom is

Determine the frequency of revolution of the electron in 2nd Bohr's orbit in hydrogen atom.

The period of revolution of electron in 3^(rd) Bohr orbit in Hydrogen atom is 4.132xx10^(-15) second.Hence find the period of revolution of electron in the fourth Bohr orbit.

Calculate the frequency of revolution of electron in the first Bohr orbit of hydrogen atom, if radius of first Bohr orbit is 0.5Å and velocity of electron in the first orbit is 2.24xx10^6m//s .

What is the velocity of electron in Bohr's third orbit of hydrogen atom ? Also calculate the number of revolutions the electron makes in Bohr's third orbit in one second.
