10. One of the key concepts in the quantum theory is the manifestation of wave-particle duality of matter in the microscopic world. In other words, a microscopic particle, such as an electron, demonstrates particle-like behavior in some circumstances and wave-like behavior in other situation.

(b) Which physical quantities are used to describe the kinetic properties (that is, properties of its motion) of a particle? And which physical quantities are used to describe the kinetic properties of a wave? How are they connected in quantum theory? (5%)
