Obstacles Block the Path of Light
Obstacles Block the Path of Light is a skill on Pengi from Sesson 2: Reflection & Visibility in Amplify Science (California) Grade 4.
Key Concepts
Because light travels in straight lines, it can be easily blocked. An object that stands between the light source and the eye acts as an obstacle.
If an obstacle interrupts the path of light —either preventing light from hitting the object or preventing reflected light from reaching the eye—the object becomes invisible to the observer. An object's visibility is entirely dependent on an clear, uninterrupted line of sight.
