Geometric Optics: Basics 

Topics

• Optics
• Lenses
• Mirrors
• Focal Length

Sample Learning Goals

• Explain how an image is formed by a converging lens or flat mirror using ray diagrams.
• Determine how changing the parameters of a lens (focal length, diameter) affects where the image is formed and how it appears (magnification, brightness, and inversion).
• Predict where an image will be formed given the object distance and optic parameters.
