Question

In atom in transition from energy state A to C 1000 Å wavelength photons are emitted and in transition from B to C energy state 5000 Å wavelength photons are emitted. What will be the wavelength of photon in transition from A to B state?

Answer 1

For transition from A to C
E_A – E_C = \(\frac{h c}{\lambda_{1}}\) ……………… (1)
For transition from B to C
E_B – E_C = \(\frac{h c}{\lambda_{2}}\) ……………… (2)
For transition from A to B
E_A – E_B = \(\frac{h c}{\lambda_{3}}\) ……………… (2)
