Answer Details
The instrument used for measuring the speed of wind is called a cup anemometer.
A cup anemometer typically consists of three or four cups mounted on a horizontal axis. The cups are designed to catch the wind and spin around the axis. The speed of the cups' rotation is proportional to the speed of the wind, and this rotation is measured and recorded by the anemometer.
Cup anemometers are widely used to measure wind speed in a variety of applications, including weather forecasting, aviation, and wind energy production. They are simple to use and provide accurate measurements, making them a valuable tool for those who need to monitor wind conditions.
