Which of the following is not conserved during Raman scattering ?
AEnergy
BMomentum
CKinetic Energy
DMass
Answer:
C. Kinetic Energy
Read Explanation:
Raman Scattering is an inelastic scattering of a photon by molecules which are excited to higher vibrational or rotational energy levels.
The process involves the energy exchange between the incident photon and the scattering molecule.
Energy Conservation: The total energy of the system (photon + molecule) is conserved during the interaction.
Momentum Conservation: The total linear momentum of the system is conserved.
Kinetic Energy: The kinetic energy of the individual photon is not conserved because the photon exchanges a portion of its energy with the molecular state, resulting in a change in frequency (wavelength) known as the Raman shift.
