Microwaves are the electromagnetic waves of wavelength of the order of a few millimeters, which is less
than those of T.V. signals. On account of smaller wavelength, the microwaves can be transmitted as beam
signals in a particular direction, much better than radiowaves because microwaves do not spread or bend
around the corners of any obstacle coming in their way. Therefore, microwaves are better carriers of signals
than radio waves.
