a photon of 3000 Angstrom is absorbed by a gas and then re-elected as two photons. One photon is red 7600  Angstrom  .  What wavelength of other photon?  Here I am knowing solution but I am not able to understand that why we are using formula ( h*c/lambda of total =  h*c/lambda of 1 +h*c / lambda of 2 ) Please solve it
