An electromagnetic wave is properly called a Transverse Electro Magnetic wave, or TEM wave. It consists of an alternating magnetic wave at right angles to an alternating electric wave, with both fields being at right angles to the direction of propagation. The plane of the electric field is defined as the plane of polarization.
A micro-strip antenna works on the principle of resonant cavity (short circuit walls on top and bottom, open circuit walls on the sides).A resonant cavity stores energy unlike transmission lines or wave guide which transmits electromagnetic energy from one part to another. A R.C is equivalent to LC device at low frequencies.
The relationship is interference is the addition of two or more wave pattern and the principle of superposition is the displacement of any point due to the superposition of wave system equal to the sum of the displacements of the individual waves at that point.
with the help of function generator we found wave in oscilloscope
an oscilloscope give amplitude v/s time display of a wave, whereas the spectrum analyzer gives amplitude v/s frequency display. the oscilloscope gives distribution of energy in wave with respect to time whereas the spectrum analyzer displays frequency components of a wave and their amplitudes.
A distortion analyzer is an electronic test instrument that measures the accuracy of an electronic circuit at reproducing a wave. For instance, an audio amplifier might have a sine wave input to it, and the distortion analyzer measures how close the output is to a sine wave. If the output is clipped, the wave will be distorted, and the analyzer will measure the amount of harmonics present. The analyzer does this by supplying a low distortion sine wave test signal which is connected to the device under test. The output from the device is connected to the input of the analyzer where the original input signal is filter out with a precision notch filter. Anything left over after filtering represents distortion components and noise. Amplifiers will frequently have a "Total Harmonic Distortion plus Noise" specification which is an accurate term for the quantity measured by a distortion analyzer. There are many manufacturers of distortion analyzers. The Hewlett-Packard models 331a and 333 are laboratory standard instruments. Other notable manufacturers are Sound Technology Corporation and Textronix.
A wave analyzer is used to analyze the frequency and amplitude of electronic signals, such as radio waves or sound waves. It helps in measuring and displaying the spectral content of the signal, making it useful in various fields like telecommunications, audio engineering, and research. By providing detailed information about the signal's frequency components, a wave analyzer aids in troubleshooting, signal optimization, and quality control.
Wave fronts are composed of many smaller wave fronts
consider a dynamiter D having a moving coil and a fixed coil. The moving coil is supplied from I/P source whose waveform is to be analysed. Fixed coil is supplied from harmonic generator. Steady deflection of dynamiter result only from those current wave forms in moving and fixed coils which have some frequency.
The principle you are referring to is the wave–particle duality principle, which suggests that particles such as electrons exhibit both wave-like and particle-like properties. This concept is a fundamental aspect of quantum mechanics.
The principle use of a wave board is for street surfing. The board is a sort of hybrid cross between a snowboard, a skateboard and a surfboard. It is very versatile and has a wide range of motion.

An echo is a sound wave that has reflected off a boundary
This statement is describing the principle of reflection, which applies to waves bouncing off a surface. According to this principle, the angle of incidence (the angle at which the incoming wave strikes the surface) is equal to the angle of reflection (the angle at which the outgoing wave leaves the surface).
No, it isn't harmful at its standard characteristics of operation.
Each type of wave has a range of frequencies. Visit this site for a good explanation- http://en.wikipedia.org/wiki/Electromagnetic_spectrum
