The Nobel Prize: The Dual Nature of Light as Reflected in the Nobel Archives
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.
Physics Classroom
The Physics Classroom: Light Waves and Color
The behavior of light waves is introduced and discussed. Also, polarization, color, diffraction, and interference are introduced and discussed thoroughly as supporting evidence of the wave nature of light.
Georgia State University
Georgia State University: Hyper Physics: Wave Particle Duality
The dualistic nature of light is discussed. The photoelectric effect and the Davisson-Germer experiment are contrasted as empirical evidence supporting each of the two views - particle and wave - of the nature of light. The photoelectric...

This resource provides a concise overview of the speed of light and the Ole Roemer, the first man to measure it.
Globio
Glossopedia: Light
Light is a form of energy. We see it in many different forms all around us. It's the sunlight that pours through your bedroom window and wakes you up. Images and in-depth information on light can all be accessed in this article.
Synopsys
Synopsys: Optics: A Gentle Intro to Optical Design: Wave Particle Duality
Discusses the manner in which light behaves as both wave and particle. This dualistic nature of light is one topic of many on the page.
National High Magnetic Field Laboratory
Magnet Academy: Timeline of Electricity and Magnetism: 1900 1909
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.
