An He1+ ion absorbs a photon with a frequency of 2.53 x 1018 Hz. If the energy of the final state is 4.35 x 10-15 J, calculate the energy of the initial state.


Expert Answer

Step 1

Frequency of photon = 2.53×1018 Hz

Energy of final state (Ef) = 4.35×10-15 J

Step 2

The change in energy can be expressed as the product of a constant that is plank’s constant(h) and frequency(ν). The mathematical expression for this is given as:
