- Option 1: Smoke

- The Ringelmann scale is specifically designed to measure the density of smoke emitted from stacks and chimneys.

- It uses a series of shaded grids to compare against the smoke's color and opacity.

- Correct Answer

- Option 2: Polluted water

- The Ringelmann scale is not used to measure water pollution.

- Water pollution is usually measured using indicators like pH, turbidity, or presence of specific chemicals.

- Option 3: Fog

- The Ringelmann scale is not applicable for fog density.

- Fog measurements are usually related to visibility and moisture content.

- Option 4: Noise

- Noise pollution is measured in decibels, not by the Ringelmann scale.

- This scale has no use for assessing noise levels.
