Physics · Wave Optics
Although water is transparent to visible light, it is not possible to see distant objects clearly in fog, which consists of fine water droplets. This is because:
- 1Fog completely absorbs all wavelengths of visible light
- 2Light rays undergo total internal reflection and cannot reach the observer's eyes
- 3Most of the light is scattered by the droplets, creating apparent opacity✓
- 4Fine droplets of water are completely opaque to visible light
Correct answer
Most of the light is scattered by the droplets, creating apparent opacity
