The dye acriflavine when dissolved in water has its maximum light absorption at 4530 Ã… and has maximum fluorescence emission at 5080 Ã…. The number of fluorescence quantum is, on the average, 53% of the number of quanta absorbed. What percentage of absorbed light energy is emitted as fluorescence?

A certain dye absorbs light of cerain wavelength and then fluorescence light of wavelength 5000 Å.Assuming 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 (in Å) : [hc=12400 eVÅ]

A certain day absorbs lights of lamda=400 nm and then fluorescence light of wavelength 500 nm. Assuming that under given condition 40% of the absorbed energy is re-emitted as fluorescence, calculate the ratio of quanta absorbed to number of quanta emitted out.

A certain dye absorbs 4000 Å and fluoresces at 8000 Å. These being wavelengths of maximum absorption that under given conditions 50 % of the absorbed energy is emitted. Calculate the ratio of the no. of quanta emitted to the number absorbed.

A certain dye absorbs light of lambda = 4000 "Å" and then flurescences light of lambda = 5000"Å" . Assuming that under given conditions 50 % of the absorbed energy is re-emitted out as fluorescence , calculate the ratio of the number of quanta emitted out to the number of quanta absorbed :

A certain dye absorbs light of lamda = 4000 Å and then fluresces light of 5000 Å . Assuming that under given conditions 50 % of the absorbed energy is re-emitted out as fluorescence, calculate the ratio of number of quanta emitted out to the number of quanta absorbed.

A certain day absorbs lights of lamda=400 nm and then fluorescence light of wavelength 500 mn. Assuming that under given condition 40% of the absorbed energy is re-emitted as fluorescence, calculate the ratio of quanta obserbed to number of quanta emitted out.

A certain day absorbs lights of lamda=400 nm and then fluorescence light of wavelength 500 mn. Assuming that under given condition 40% of the absorbed energy is re-emitted as fluorescence, calculate the ratio of quanta obserbed to number of quanta emitted out.

A certain dye absorbs 4530A^(@) and fluoresence at 5080A^(@) these being wavelength of maximum absorption that under given condition 47% of the absorbed energy is emitted. Calculate the ratio of the no of quanta emitted to the number absorbed.
