A photon of 300 nm is absorbed by a gas which then
re-emits two photons. One re-emitted photon has
wavelength of 496 nm. Wavelength of other re-emitted
photon is
re-emits two photons. One re-emitted photon has
wavelength of 496 nm. Wavelength of other re-emitted
photon is
View answer and explanation
Correct option: C
759 nm
Option C (759 nm) is correct because the energy of the absorbed photon must equal the sum of the energies of the two re-emitted photons.
