Amplitude and Frequency Modulation

Introduction: The method of modifying the carrier signal in response to the message signal is known as modulation. In the process of modulation, the high-frequency sine wave signal is referred to as the carrier signal. The modulating signal is the name given to the output signal. Modulation is a signal processing technique that involves shifting […]

Vibration of Strings and Air Columns

The particles of a medium undergo multiple simultaneous displacements when multiple waves arrive at the exact location in the medium simultaneously. A new wave motion is created due to the vector sum of all the displacements (since displacement is a vector). A wave superposition happens when two or more waves are combined to create a

superposition

Superposition is the process of combining the impacts of two (or more) waves at the same time and place. This provides us the sum of the two waves’ effects. Although the theory of superposition works for non-material waves, “effect” denotes “displacement” for material waves (such as electromagnetic waves, the pressure interpretation of sound waves, and

Principle of superposition of waves

Introduction: Imagine you and your friend are holding a piece of string from both ends. Once the string is stretched tight, both of you start moving it up and down with your hand from your respective ends. We know that plucking of the string would lead to oscillations/harmonic waves. But, since this activity is being

Principle of Superposition of Waves

When stating the principle of superposition of waves, we learn that the resultant displacement of multiple waves in a medium at a specific point is the vector summation of different displacements. These individual displacements relate to every wave at a specific point. Read on to learn more about the principle of superposition of waves. Principle

Destructive interference

In physics, interference is a phenomenon in which two waves superpose to generate a consequent wave of greater, lower, or the same amplitude. Constructive and destructive interference emerge from the interaction of waves that are correlated or coherent with one another, either because they come from the same source or because they have the same

Coherence’s Applications

When a number of waves travelling in a medium simultaneously, with each wave being independent of the other, their effects get added together. The resultant wave is obtained by the superposition principle of waves which states that when a number of waves in a medium superpose each other, resultant displacement at any given point at
