35 slide PowerPoint presentation - good introduction to Quantum Mechanics - covers the following:
• early scientists' views on the nature of light (particle vs. wave).
• on the atomic level, energy and matter exhibit the characteristics of both waves and particles.
• on the atomic level, energy is emitted or absorbed in discrete amounts called photons.
• the energy of a photon is directly proportional to the frequency of radiation.
• the energy of a photon is inversely proportional to its wavelength.
• the photoelectric effect shows that a photon with zero mass has kinetic energy.
• the quantum theory can explain the photoelectric effect, the wave theory cannot.
• the Compton Effect, in terms of the momentum and energy of the photon.
• the similarities and differences between early models of the atom and the people responsible for these models.
• experiments that demonstrate the particle-like properties of electromagnetic radiation.
• the structure of the atom.
• the difference between emission and absorption spectra.
• the mass-energy relationship.
• mass-energy is conserved at all levels, from cosmic to subatomic.
• the Standard Model of Particle Physics has evolved from previous attempts to explain the nature of the atom and that it states:
- atomic particles are composed of subnuclear particles.
- the nucleus is a conglomeration of quarks which manifest themselves as protons and neutrons.
- each elementary particle has a corresponding antiparticle.
