Understanding Weathercocks
A weathercock, also known as a weather vane, is a device used to indicate the direction of the wind. However, it does not measure the speed of the wind accurately. Here’s why option 'D' is false:
Limitations of Weathercocks
- Weathercocks primarily indicate wind direction, not speed.
- They can only show which way the wind is blowing but do not provide quantitative data on wind velocity.
How Wind Speed is Measured
- To measure wind speed accurately, an anemometer is used.
- Anemometers consist of rotating cups or blades that turn faster with higher wind speeds, providing a numerical value for wind speed.
Common Misconceptions
- It’s a common misconception that weathercocks can indicate how fast the wind is blowing.
- While they can sway and move with the wind, their primary function is directional guidance.
Conclusion
- Therefore, option 'D' is incorrect because a weathercock does not show the accurate speed of the air movement; it only indicates the wind direction. For precise wind speed, one would need a different instrument, such as an anemometer.
