A dye absorbs a photon of wavelength `lambda` and re`-` emits the same energy into two phorons of wavelengths `lambda_(1)` and `lambda_(2)` respectively. The wavelength `lambda` is related with `lambda_(1)` and `lambda_(2)` as `:`

Options

A. `lamda=(lamda_(1)+lamda_(2))/(lamda_(1)lamda_(2))`
B. `lamda=(lamda_(1)lamda_(2))/(lamda_(1)+lamda_(2))`
C. `lamda=(lamda_(1)^(2)lamda_(2)^(2))/(lamda_(1)+lamda_(2))`
D. `lamda=(lamda_(1)lamda_(2))/((lamda_(1)+lamda_(2))^(2))`
