Optics - General Introduction - Why we need different approaches

  • Optics is the branch of physics that deals with the behavior and properties of light
  • Light is a form of electromagnetic radiation that is visible to the human eye
  • It plays a crucial role in our daily lives and has applications in various fields such as medicine, telecommunications, and astronomy
  • Understanding the behavior of light is essential to explain phenomena like reflection, refraction, and interference
  • Different approaches are used in optics to study and explain these phenomena
  • These approaches include the ray optics, wave optics, and quantum optics
  • Each approach provides a different perspective and mathematical framework to analyze and predict the behavior of light
  • The choice of approach depends on the specific phenomenon being studied and the level of accuracy required
  • In this lecture, we will explore these different approaches and understand why they are necessary
  • Let’s start by looking at the basics of ray optics and its applications
