Wind speed is measured using an anemometer. It is typically made up of cups attached to spindle. The stronger the wind the faster the cups rotate and the higher the reading. Several readings should be taken over a couple of minutes and an average taken. The measurement is sometimes made in knots but any speed unit is possible.

a wave propagated at the speed of light by the periodic variations of electric and magnetic fields. electromagnetic wave. A wave of energy consisting of oscillating electric and magnetic fields. Radio waves, light waves, and x-rays are electromagnetic waves.
A light wave is an example of an electromagnetic wave. A transverse wave is a moving wave that is made up of oscillations happening perpendicular to the direction of energy transfer. It can also mean that it is a wave that causes the medium to vibrate at right angles to the direction in which the wave travels.
