Optics is the study of light and its behavior when it interacts with different materials.
a. Reflection and Refraction
- Reflection: When light bounces off a surface.
- Refraction: When light passes through a medium and bends due to a change in speed.
b. Lenses and Mirrors
- Lenses and mirrors bend light to focus or redirect it, forming images.
- Snell’s Law: Describes how light bends as it passes from one medium to another.
c. Wave Optics
- Describes light as a wave and includes phenomena like interference, diffraction, and polarization.
- Young’s Double Slit Experiment: Demonstrates the wave nature of light.
