According to the bohr model of a hydrogen atom, the frequency of light radiated by an electron moving from an orbit n1 to an orbit n2 corresponds to the energy level difference between n1 and n2 of e=e0(1n21−1n22), where e0=−mez2e432π2ϵ20ℏ2, and where me is the electron mass, z is the atomic number, e is the magnitude of the electron charge, ϵ0 is the permittivity of free space, and ℏ is planck's constnt divided by 2π. in the case of hydrogen (z=1) e0=−13.6ev.

part a: find the frequency of light f radiated by an electron moving from orbit n1=2 to n2=1 inside of a he+ ion.
part b: in the bohr model of hydrogen, the radius of the nth orbit is defined as rn=a0n2z, where a0==5.29

Answer: fn = wcos50 = 38.89(9.81)(cos50) = 245.23 n

Iwould sure like to answer your question but i honestly just don’t know

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.

Hi, your answer is not correct. this is a cumulative
