A molecule absorbs a photon of wavelength 240 nm and re-emits the energy as three photons. If two of the emitted photons have wavelengths 720 nm and 1080 nm, the wavelength of the third photon is
Options:
Answer:
B
Solution:
Energy is conserved: 1/240 = 1/720 + 1/1080 + .
LCM 2160: 9/2160 = 3/2160 + 2/2160 + .
, so nm.
Answer: (B).
