Superposition of wave

Superposition of waveIntroduction : We are well aware of the parameter of a wave such as amplitude, frequency, wavelength, etc. Superposition of the wave is well understood by amplitude of a wave. Interesting phenomenon of superposition of a wave is due to two or more wave...

Expression of a progressive wave

Equation of a progressive waveWe are well aware of  a progressive wave, that a progressive wave continuously move in forward direction in a given medium without change in form. Since it is a progressive wave we need to understand this wave in form of time and displacement....
