A wave in physics is a moving disturbance in the energy level of a field.
A transmitter is an electronic device that generates and amplifies a carrier wave, modulates it with a meaningful signal derived from speech, music, TV or other sources, and broadcasts the resulting signal from an antenna.
The antenna is an apparatus to receive or transmit electromagnetic waves and convert respectively to or from an electrical signal.
Receiver is one of the several electronic devices that receive electromagnetic waves, or signals transmitted as such.
Therefore, the correct description of a transmitter, a receiver and an antenna is given above.

two harmonic waves are described by y1= (4m) sin (8/mx-300/s t) y2=(4m) sin (8/mx-300/s t-2) what is the wavelength of the resultant wave ?
The combined wave has a wavelength of 0.785 meters, which is the same as the combined wavelength of the two component waves. Duration is the interval between a wave's summit or valley and the succeeding wave.
What is a wave length?The distance between two successive peaks or troughs of a wave is measured in terms of its wavelength. It is often measured in meters, centimeters, or nanometers and is the inverse of frequency. The length of a wave is the distance it travels before repeating its pattern.
⇒ y₁ = ( 4 m)sin ( (8x/m) - (300t/s) )
⇒ y₂ = ( 4 m)sin ( (8x/m) - (300t/s) - 2 )
⇒ 0.785 m
