Light can travel in three ways from a source to another location: (1) directly from the source through empty space; (2) through various media; and (3) after being reflected from a mirror. 1.2: The Law of Reflection
1: The Nature of Light. In this chapter, we study the basic properties of light. In the next few chapters, we investigate the behavior of light when it interacts with optical devices such as mirrors, lenses, and apertures.
Summary. Light is a transverse, electromagnetic wave that can be seen by the typical human. The wave nature of light was first illustrated through experiments on diffraction and interference. Like all electromagnetic waves, light can travel through a vacuum. The transverse nature of light can be demonstrated through polarization.
30 Μαΐ 2023 · Key Equations. Summary. 1.1: The Propagation of Light. The speed of light in a vacuum is \ (\displaystyle c=2.99792458×10^8m/s≈3.00×10^8m/s\). The index of refraction of a material is \ (\displaystyle n=c/v\), where v is the speed of light in a material and c is the speed of light in a vacuum.

INTRODUCTION. ght and quanta. Hoffmann’s amusing and in-formative account—involving in part the wave-particle twins “tweedledum” and “tweedledee”—captured nicely the level of frustration felt in those days about the true . ature of light. And today, some 60 years later, the puzzle of tweedledum and tweedledee linger. .What is light? W.
In the early 1800s, Thomas Young provided clear evidence that showed that light exhibits properties consistent with wave behavior; specifically showing that it exhibits patterns of constructive and destructive interference. Our modern understanding of light has built on the work of Young and others.
