Kagune and conjugation

Chemistry Level pending

Kaneki Ken needs your help! The kagune he possesses has turned invisible, and you have been tasked to determine why!

Assuming the energy levels of a conjugated system are just like a 1 dimensional box, derive a relation to find the wavelength of light emitted during a transition between frontier orbitals. Also the length of the box can be assumed to be \( (N+1)L\), where \(N\) is the number of Carbon atoms and \(L\) is the bond length of the C-C bond.

Using this relation,

Find the greatest integer of the wave number of emitted light by ethene in centimeter inverse, if C-C bond length is 1.34 angstroms.


Is Kaneki's kagune really invisible?
