Overview
Optics is the branch of science that deals with light, its properties, and its behavior when it interacts with various materials and surfaces. Light is a form of energy that travels in the form of waves and does not require any medium for propagation. In this chapter, we explore how light behaves wh
Key Concepts
Light is a form of energy
Light is a form of energy that travels in straight lines (rays) and can travel through vacuum at a speed of 3 × 10⁸ m/s. Light exhibits wave propertie
Refraction is the change in direction
Refraction is the change in direction of light when it passes obliquely from one transparent medium into another. This occurs because light travels at
When white light (composite light) passes
When white light (composite light) passes through a transparent medium like a glass prism, it splits into its component colors forming a spectrum - th
Scattering of light is the process
Scattering of light is the process by which light is redirected in all directions when it interacts with particles in a medium. The particle causing s
A lens is an optically transparent
A lens is an optically transparent medium bounded by two spherical surfaces (or one plane and one spherical surface). Convex lenses are thicker at the
Learning Objectives
- State and apply the laws of refraction in solving optical problems
