Which among the following instrument is used for measuring wind speed ?
-
Anemometer
-
Hygrometer
-
Spectrometer
-
Hydrometer
A
Correct answer
Explanation
An anemometer is the scientific instrument specifically designed to measure wind speed and wind pressure. It typically consists of cups or propellers that rotate with the wind, with the rotation speed directly proportional to wind velocity. Hygrometers measure humidity, spectrometers analyze light spectra, and hydrometers measure liquid density.
