This PowerPoint presentation summarizes key information about light, including its nature, history of theories about it, characterization, sources, laws, and transmission. Light is an electromagnetic wave that can travel freely through space. Historically, theories described light as particles, waves, and electromagnetic radiation. Light exhibits properties of polarization, coherence, and interference. Natural light sources include the sun, stars, and fire, while artificial sources are light bulbs, neon signs, and candles. Laws of reflection and refraction govern how light interacts with surfaces and changes direction when passing between mediums of different densities. Light can be transmitted through transparent, translucent, or opaque materials. The presentation was created by five students at BaStateU ARASOF
