A seismograph can locate a seismic wave.

When alternating current of any frequency is fully rectified, both halves of the wave are converted to direct current and utilized. Half-wave rectification is when half of the wave is ignored. So the main characteristic that is changed is the shape of wave by flipping half the wave over to the same side as the rest. But it does not flatten the peaks on the wave without additional filtering.
Unlike humans, insects have the ability to see ultraviolet wave lengths. The champions at sensing infrared radiation are believed to be the beetles.
Wave action and tidal currents are being utilized today to produce electrical energy.
Wave energy has been utilized by humans for centuries, but the first recorded use of wave power for electricity generation was in 1881 by a French physicist named Gustave-Éiffel. He used wave energy to power the lighting in his house.
By hunting passively. they just wave around their tentacles and hope for something to come in contact with it.
many animals ( dolphins, bats, insects, etc.) use sonic (sound) wave to locate positions, food,etc. By studying these animals we can find out how to use and read sonic waves and how they relate to different locations, movements, solids, liquids, gases,etc.
X-Rays locate cavities in our teeth
It indicate how well the input transformer is being utilized. It is given by the ratio of DC output power to the AC power rating of Transformer.
Cutting circuits are utilized to choose for purposes of transmission, that part of a sign wave structure which lies above or beneath a specific reference voltage level.
