# 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.

**Bonus**

Is Kaneki's kagune really invisible?
