Final answer:
An anemometer is a device used to measure wind speed. It is commonly used in meteorology and weather forecasting to determine the speed of wind in a given area.
Step-by-step explanation:
An anemometer is a device used to measure wind speed. It is commonly used in meteorology and weather forecasting to determine the speed of wind in a given area. Anemometers can be mechanical or electronic, and they work by measuring the force of the wind on different components of the device, such as rotating cups or a spinning propeller. The rotation or movement of these components is then converted into a measurement of wind speed.
