Teal electron ko ring-to-ring drag karo, ya neeche n = 1 se n = 4 choose karo; camera ko side aur top se rotate bhi kar sakte ho.
Bohr model ko 3D me explore karo: hydrogen ke stationary electron orbits, n² ke according radius, changing speed, energy aur angular momentum dekhho. Electron ko ring-to-ring drag karke permitted states samjho, phir n = 4 se n = 1 direct emission aur n = 1 se n = 4 absorption ko frozen transitions me compare karo. Exact 12.75 eV photon energy aur ek direct jump se exactly one photon ka rule model me clearly freeze hota hai.
In the Bohr model, when the single electron in hydrogen makes a direct transition from n = 4 to n = 1, how many photons are emitted and what is their energy?
