Where φ shows the phase difference that is present between the waves in radians Take the case of another wave with a different phase travelling to the right but with the same frequency and amplitude. Furthermore, k = 2π/λ is the wavenumber and ω = 2πf refers to the angular frequency of the wave.
The expression of the amplitude of a sinusoidal wave travelling to the right along the x-axis is as,
Moreover, the derivation of the formula for the sum of two waves is as follows: Furthermore, this concept is called destructive interference. Similarly, if the meeting of a crest of a wave takes place with the trough of another wave, then the resultant amplitude turns out to be equal to the difference in the individual amplitudes. Furthermore, this concept is called constructive interference. In accordance with the principle of superposition of waves, if the meeting of a crest of a wave takes place with the crest of another wave of the same frequency at the same point, then the resultant amplitude turns out to be the sum of individual amplitudes. Interference Of Waves Derivation of Interference of Waves The principle of superposition of waves explains that when two or more similar type propagating waves are incident on the same point, the resultant amplitude at that point happens to be equal to the vector sum of the amplitudes of the individual waves. Furthermore, interferograms refer to the resulting images or graphs. One can observe the interference effects with all types of waves, for example, gravity waves, radio, light, surface water waves, or matter waves. Furthermore, the occurrence of constructive interference and destructive interference takes place from the interaction of waves that have a correlation with each other, either because they have the same or nearly the same frequency or they come from the same source. Depending on the alignment of peaks and troughs of the overlapping waves, the waves can cancel each other either partially or entirely. Interference takes place when two or more waves meet each other. Moreover, the reason for this shape is due to the net effect of the two individual waves upon the medium particles. Furthermore, the interference of waves makes the medium take on a particular shape. Interference of waves refers to the phenomenon whose occurrence takes place when two waves meet while travelling along the same medium.
