to transfer large blocks of energy over long distance, which equal to half of electromagnetic wave length. (at 50 Hz approximately is 3000 km.)
A device that converts full wave signal to half wave rectified dc signal. The device operates only for half of the input cycle during which the input signal is alllowed to pass and stops transmission of the signal for other half cycle. ok?
You use a half-wave rectifier where the system design does not require a full-wave approach. Half wave rectifier output is used for running ac motors.
In a properly designed and terminated transmission line, the electrical length is infinity. Any discontinuity in the line, such as an open, short, or change in impedance, results in a reflection of the travelling wave in the line. That reflection distorts the original signal and, if big enough, can damage things, like the transmitter.
As states half wave will rectify only either positive or negative of a full wave. full wave will rectify positive and negative making it full wave rectification.
The characteristic impedance or surge impedance belongs to a uniform transmission line, usually written Z0. It is the ratio of the amplitudes of a single pair of voltage and current waves propagating along the line in the absence of reflections.

Half- and full-wave rectifiers are used to convert AC into DC. That is the primary use of the rectifier in industrial applications. AC is used across the power grid, but to use electricity for welding, electroplating, electrorefining (of metal) and as a DC source for motors with special speed controls, the AC must be changed (rectified) to DC.

You might need to use the wave to help control the applications. This will help you to know when to make more products.

The distance between the line of origin and the crest/trough of a wave is called the amplitude of the wave.
A half wave rectifier does not make a stable voltage. A single phase half wave creates a "bumpy road" where voltage modulates between sine wave maximum and zero. A three phase half wave will create a more stable, but ultimately "unclean", voltage.
As states half wave will rectify only either positive or negative of a full wave. full wave will rectify positive and negative making it full wave rectification.
