Optics Key Concepts

Study Notes

The study of the behavior and properties of light, including its interactions with matter
Branches:
- Geometrical optics: deals with the behavior of light as it travels through media
- Physical optics: deals with the nature of light itself
Important phenomena:
- Reflection: change in direction of light at a surface
- Refraction: bending of light as it passes through a medium
- Diffraction: bending of light around an obstacle
- Interference: superposition of light waves

The study of motion, forces, and energy
Branches:
- Kinematics: describes the motion of objects without considering forces
- Dynamics: studies the motion of objects in relation to forces
- Statics: studies objects at rest
Important concepts:
- Newton's Laws:
  - First Law: inertia, an object at rest remains at rest, an object in motion remains in motion
  - Second Law: force is equal to mass times acceleration
  - Third Law: every action has an equal and opposite reaction
- Energy:
  - Kinetic energy: energy of motion
  - Potential energy: energy of position or stored energy
- Momentum: product of mass and velocity

The study of the behavior of matter and energy at the atomic and subatomic level
Principles:
- Wave-particle duality: particles can exhibit both wave-like and particle-like behavior
- Uncertainty principle: cannot know certain properties of a particle simultaneously with infinite precision
- Superposition: a particle can exist in multiple states simultaneously
Important concepts:
- Schrödinger equation: mathematical equation describing the behavior of quantum systems
- Wave function: mathematical description of a quantum system
- Quantization: energy is quantized, meaning it comes in discrete packets (quanta)

Study of light behavior and properties, including interactions with matter
Divided into two branches: geometrical optics (light behavior through media) and physical optics (nature of light itself)
Important phenomena:
- Reflection: change in direction of light at a surface
- Refraction: bending of light as it passes through a medium
- Diffraction: bending of light around an obstacle
- Interference: superposition of light waves

Study of motion, forces, and energy
Divided into three branches: kinematics (motion without forces), dynamics (motion with forces), and statics (objects at rest)
Important concepts:
- Newton's Laws:
  - First Law: inertia (objects at rest remain at rest, objects in motion remain in motion)
  - Second Law: force equals mass times acceleration
  - Third Law: every action has an equal and opposite reaction
- Energy:
  - Kinetic energy: energy of motion
  - Potential energy: energy of position or stored energy
- Momentum: product of mass and velocity
