Rectilinear Propagation of Light
Learning Objectives
- Students will be able to state that light travels in straight lines in uniform media
- Students will be able to use ray model to explain light paths
- Students will be able to construct light ray diagrams for various situations
Core Concepts
- straight_line_propagation
- ray_model
- uniform_medium
- ray_diagram
- light_path
Interesting Fact
Light from the Sun travels in essentially straight lines across the solar system until reaching and passing through atmospheres
Key Scientist
Alhazen (Ibn al-Haytham)
Studied light propagation and vision with detailed optical experiments
Philosophy
Light propagates in straight lines through uniform space. This rectilinear propagation is a fundamental property of light, rather than a philosophical principle.
