a photon of 300nm is absorbed by a gas and then remits two photons .one re- emitted photon has wave length 496nm the wavelength of second re-emitted photon is |
|
Answer» Answer: Given:
Wavelenghth of absorbed photon, λ = 300 NM
Wavelenghth of re-emitted photon, λ1 = 496 nm
Wavelenghth of re-emitted photon, λ2 = x nm
We know,
ETotal = E1 + E2
STRAIGHT E space EQUALS hc over straight lambda hc over straight lambda subscript space equals hc over straight lambda subscript 1 plus hc over straight lambda subscript 2 1 over straight lambda space equals space 1 over straight lambda subscript 1 plus 1 over straight lambda subscript 2 1 over 300 equals 1 over 496 plus 1 over straight lambda subscript 2 1 over straight lambda subscript 2 space equals 1 over 300 MINUS 1 over 496 1 over straight lambda subscript 2 space equals 0.00131 straight lambda subscript 2 space equals 759.18 space nm
Wavelength of the other photon is 759.18 nm |
