Light Intensity and Distance: Exploring LED Behavior

This lecture discusses the relationship between light intensity and distance, specifically focusing on red LEDs. The instructor explains how the intensity of the red LEDs increases as the distance to a hindrance decreases. As the hindrance is approached, the LEDs shine more brightly, demonstrating a clear correlation between proximity and light intensity. The lecture also highlights the effect of removing the hindrance, which further enhances the brightness of the LEDs. Conversely, as the distance from the hindrance increases, the intensity of the light diminishes. The instructor revisits these concepts to reinforce the understanding of how light intensity varies with distance, providing a clear and practical example of this phenomenon in action.
