Today's Recorded science class: 10 th standard  Metallurgy  🇴 🇴 🇴 🇴 🇴 🇴 🇴 🇴 🇴 🇴 🇴 🇴 🇴 🇴  Here’s an introductory lecture on Reflection and Refraction of Light suitable for students: ---  Introduction to Light, Reflection, and Refraction  What is Light? Light is a form of energy that travels in waves and enables us to see the world around us. It is a type of electromagnetic radiation that moves at an incredibly high speed—about 299,792 kilometers per second in a vacuum. Light can behave both as a wave and as a particle, a concept known as wave-particle duality. Why Study Light? Understanding how light interacts with different materials is essential. This interaction can result in various phenomena such as seeing images in mirrors, lenses that help us focus light, and even the creation of rainbows. Two fundamental processes in the study of light are *reflection* and *refraction*. ---  Part 1: Reflection of Light What is Reflection? Reflection is the p...
