Question

What is the energy and frequency of the photon emitted during the transition from the orbit of n = 4 to that of n = 2 in hydrogen atom​

Answer 1

Explanation:

We want to calculate the frequency, wavelength and energy of the emitted photon, when the atom makes a transition from ni = 4 to nf = 2. = −13.6 × 3 16 eV = 2.55 eV.
