According to Bohr's theory the ratio of time taken by electron to complete one revolution in first excited and second excited states of hydrogen will be:

According to Bohr's theory, the ratio of the times taken by the electron in a hydrogen atom to complete one revolution in orbits corresponding to ground and first excited states is

Time taken by an electrons to complete one revolution in the Bohr orbit of the H atom is

Time taken by an electrons to complete one revolution in the Bohr orbit of the H atom is

The time taken for an electron to complete one revolution in Bohr orbit of hydrogen atom is-

Time taken for an electron to complete one revolution in the Bohr orbits of hydrogen atom is
