Light and Optics Lesson

Introduction to Light and Optics

Light is a type of electromagnetic wave that travels through space. It allows us to see the world around us. Optics is the branch of physics that deals with the behavior of light and its interactions with different materials, such as lenses, mirrors, and prisms.

Key Concepts

• Reflection: The bouncing of light off a surface, such as a mirror.
• Refraction: The bending of light as it passes from one material to another (e.g., from air into water).
• Lens: A transparent object that bends light rays to focus or disperse them. Convex lenses converge light, while concave lenses diverge light.
• Prism: A transparent object that bends light and can split it into its component colors (spectrum).
