SSC Selection Post 2019 PYQ — Question 50

The correct answer is Option 1 i.e. Anemometer.

An anemometer is an instrument used to measure the force and velocity of wind. It is commonly used in meteorology, aviation, and environmental studies to assess wind speed and direction. The most widely used type is the cup anemometer, which consists of rotating cups mounted on horizontal arms; the speed of rotation indicates wind velocity. Other types include vane anemometers and hot-wire anemometers. Accurate wind measurement is essential for weather forecasting, wind energy assessment, and ensuring safety in maritime and aeronautical operations.
