Question

An atom absorbs a photon with wavelength 500 nm and subsequently emits a photon with wavelength 660 nm.

a) Determine the energy absorbed by the atom.

b) Assume that the atom is a solid particle with mass 3.3×10−26 kg and is initially at rest. Determine the speed of the atom after it has emitted the photon, assuming that any additional energy it acquired only contributed to its motion.

Can you do part b step by step, which equations are required?
