3) The dye Acriflavine, when dissolved in water, has its maximum light absorption at 4530 A and the maximum fluorescence emission at 5080 A. The number of fluorescence quanta is, on the average, 53% of the number of quanta absorbed. Using the wavelengths of maximum absorption and emission, what percentage of absorbed energy is emitted as fluorescence? (A) 100% (B) 47% (C) 36% (D) 12%

    can you please explain how do you calculate energy fraction because here it is given that 53%of quanta absorbed

    eduncle-logo-app

    and here 53%is multiplied by emitted energy

    eduncle-logo-app

    yes, wait

    eduncle-logo-app

    check it

    eduncle-logo-app

    here 53%energy absorbed from total energy of one photon so energy of one photon is multiplied by 0.53
