Instructional module focusing on light. Discussion includes historical development of particle versus wave theories and the scientific studies leading to the understanding of light waves today. Site also includes an interactive practice...

This article discusses the historical figures who contributed to our understanding of the nature of light, x-rays, Quantum ElectroDynamic (QED) theory, and so on.

Acting as part of an overview on quantum theory, this section of the site answers the question, what is light? In answering the question, specific discussion is directed toward light waves and theories of light.

To provide an explanation of standing waves in intruments and how music is produced with particle pitches and timbres

An explanation of Niels Bohr's (1885 - 1962 CE) Model along with an app that illustrates a hydrogen atom according to the particle or wave model. You can choose a principal quantum number "n." The right part of the graphic represents the...

This site from The Nobel Foundation tells the scientific work which earned Louis de Broglie the Nobel Prize in Physics. Here, you can read the Presentation Speech in which Professor C.W. Oseen praises Louis de Broglie's work and de...

Although it is arguably the most successful theory in physics, quantum physics has often baffled and confounded both its practitioners and the general public. This informative website discusses the types of mysteries, which still plague...

[Free Registration/Login may be required to access all resource tools.] Students will understand the photoelectric effect and that light has both particle and wave properties. Includes a simulation for exploring the photoelectric effect.

This biographical note on Wilhelm Conrad Rontgen describes his boyhood, upbringing, education, scientific work and accomplishments. Focuses on his studies of Xrays.

After an introduction, this site breaks down into sections discussion quantum theory, including A Quantum Theory for Energy, A Quantum Theory for Atomic Structures, Waves or Particles, Quantum Mechanics, and Interpreting the Quantum World.

As part of the General Chemistry Virtual Textbook, this site examines a list of related topics (in hyperlink format) on the atom and the Periodic Table of elements. Topics from light, particles, and waves to the Bohr model, quantum...

See how light knocks electrons off a metal target, and recreate the experiment that spawned the field of quantum mechanics. Describe how the results lead to the photon model of light.

A short sketch of the life and work of Thomas Young (1773-1829 CE). Traces early upbringing and education and his scientific discoveries and contributions.

This essay from the NOVA Web site explores the impact Einstein made on physics and most everything we know about the cosmos.

Albert Einstein publishes his special theory of relativity and his theory on the quantum nature of light, which he identified as both a particle and a wave. With ever new appliances, electricity begins to transform everyday life.

A page at the Isaac Newton (1642-1727 CE) Institute for the Mathematical Sciences website. This page, the contents of which come from the Microsoft Encarta encyclopedia, describes the upbringing, the education, the scientific and...
