uA switching converter that changes an ac supply to the ac supply with a different voltage, frequency, phase, or shape is called an AC/AC converter or changer.
It is the velocity of electromagnetic waves in the waveguide. Group velocity is denoted by the symbol Vg.
The signal through wave guide is propagated by different modes which are explained as below.
Waveguide is the type of transmission line which carries microwave frequencies from source to load.
We know that when an atom absorbs extra energy and goes in excited state.
As shown in the given diagram the saw filter consists of a piece of quartz crystal material on the surface of which the metallic fingers are engraved.

The RUBY MASER consist of a ruby crystal kept in the cavity.
The ward radar means radio direction and ranging. Radar is a system which is used to find out the direction of the target.
Optical rays are the single line or narrow beam of light from a small or distant source.
The process of using different wavelengths to transmit different data just as is done in regular radio transmission is called wavelength multiplexing.
