A certain dye absorbs light of certain wavelength and then fluorescence light of wavelenth 5000 armstrong. Assunming that under given conditions, 50% of the absorbed energy is re-emitted out as fluorescence and the ratio of number of quanta emitted out to the number of quanta absorbed is 5:8, find the wavelength of absorbed light.
