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 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.
Wave action and tidal currents are being utilized today to produce electrical energy.
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.
By hunting passively. they just wave around their tentacles and hope for something to come in contact with it.

A diode affects a sine wave by allowing current to flow only in one direction, effectively clipping or rectifying the wave. When an AC sine wave is applied to a diode, it will only pass the positive half of the wave, resulting in a pulsating DC output. This process can introduce distortion and create harmonics in the waveform, altering its original shape. In applications like signal demodulation, this property is utilized to extract information from the sine wave.
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.
