But the exact nature of light, and how it travels, has long puzzled scientists. One question in particular has vexed thinkers from Issac Newton to Albert Einstein: Is light a particle or a wave?

In this chapter discussions on the properties of light cover the dual wave-particle nature of light, the speed of light in different materials, reflection, refraction, and polarization. These concepts ...

Light's quantum behavior is well established, with over 100 years of experiments showing it can exist in both wave and particle form. But our fundamental understanding of this quantum nature is ...

The nature of industrial particles depends ... According to Mie theory, particle scattering is enhanced when particle size and light wavelength are similar (Bohren & Huffman 1983).
