How many time does the electron go round the first bohr orbit of hydro

1.	How many time does the electron go round the first bohr orbit of hydrogen atoms in `1 s`?
Answer» Here we have to fine the frequency which is given as `f = (mZ^(2)e^(4))/(4 epsilon_(0)^(3)h^(3))` `= (9.1 xx 10^(-31) xx l^(2) xx (1.6 xx 10^(-19))^(4))/(4 xx (8.85 xx 10^(-12))^(2) xx l^(3) xx (6.6 xx 10^(-34))^(3))` `= 6.62 xx 10^(15)Hz`
