![]() ![]() This indicates that the sources’ waves have the same frequency and the constant phase difference between them. If the sources are coherent, the superposition of waves from two sources results in a visible fixed (stationary) interference pattern. Superposition occurs at every point when waves from two sources spread out and cross across a region of space, resulting in interference. The superposition resembles another wave of the same frequency if the waves are coherent- if they all have the same frequency and a constant phase difference. ![]() For example, little ripples on a pond whose amplitude is far less than their wavelength are suitable for water waves. When the amplitudes are tiny, this is frequently the case. The medium through which the waves travel acts linearly, which means that when a portion of the medium has twice the displacement, it has twice the restoring force.Waves of the same type are superimposed.We can apply the principle of superposition of waves to any set of waves as long as we ensure that the following conditions are met: The concept at play here is the Principle of Superposition of Waves. But, since this activity is being carried out from both ends, these waves would pass through each other at some point, i.e., superposition of waves, leading to interference. We know that plucking of the string would lead to oscillations/harmonic waves. Once the string is stretched tight, both of you start moving it up and down with your hand from your respective ends. Imagine you and your friend are holding a piece of string from both ends. ![]()
