Study Notes
Electromagnetic Radiation
- Forms of electromagnetic radiation that exhibit similar properties to light include radio waves, microwaves, X-rays, and gamma rays.
Optics
- Optics is the branch of physics that studies the behavior and properties of light, including its interactions with matter.
Models of Light
- Geometric optics treats light as a collection of rays that travel in straight lines and bend when they pass through or reflect from surfaces.
- Physical optics is a more comprehensive model of light that includes wave effects such as diffraction and interference.
Challenges of Electromagnetic Descriptions
- Complete electromagnetic descriptions of light are often difficult to apply in practice due to the complexity of light's behavior and the need for simplifying assumptions.
Types of Optics
- Physical optics includes wave effects such as diffraction and interference that cannot be accounted for by geometric optics.
