Understanding Light and Optics

Key Takeaways: Light, spanning 400nm to 700nm, is vital for vision, traveling at 3 X 10^8 m/s. Optics studies light-matter interactions, including reflection and refraction. Reflection follows the law of equal angles, while refraction obeys Snell’s Law. Total Internal Reflection occurs beyond a critical angle, reflecting light entirely. Understanding light and optics has broad applications […]
