Question

The instrument used to measure the speed of the wind is

• A. Altimeter
• B. Anemometer
• C. Chronometer
• D. Dosimeter

Answer 1

The Correct Option is B

The instrument used to measure the speed of the wind is known as an Anemometer. This device is specifically designed to capture wind speed by using rotating cups or blades that spin with the force of the wind. The faster the wind blows, the faster the rotation, which is then converted into a speed measurement.

Other options provided include:

Instrument	Function
Altimeter	Measures altitude
Chronometer	Measures time with great accuracy
Dosimeter	Measures exposure to radiation

As seen, each of these instruments has a distinct purpose, with none relating to wind speed measurement except the anemometer.
