الصوت والضوء: قانون التربيع العكسي في الضوء

The video tutorial explains the inverse square law in light, stating that illumination intensity is inversely proportional to the square of the distance from the light source. It highlights two main factors affecting illumination: the light source's power and the distance from the surface. The tutorial demonstrates how changing the distance impacts illumination, showing that doubling the distance reduces intensity to a quarter, halving the distance increases it fourfold, and tripling the distance reduces it to a ninth.
