Superposition  A phenomenon like standing waves, diffraction, and interference can be explained by the superposition principle. The superposition principle works on any type of wave such as electromagnetic waves, sound waves, water surface waves, etc. but it works in some conditions.  Superposition conditions  The superposition principle is applicable on two waves such that The waves […]

Many musical instruments consist of an air column enclosed inside a hollow metal tube. Sometimes the metal tube may be more than a metre in length; it is often curved upon itself one or more times to conserve space.   Organ Pipe  The mouthpiece was not designed; pipes were set in broad daylight spaces like the

Standing waves are a type of waves that are created when two objects with different masses move through a fluid (like water) at different speeds. The different rates cause the two objects to create interference patterns that create standing waves. Standing waves can be very annoying, especially when created in small spaces. They cause the

In physics, sound is a vibration which travels through a transmission medium such as a gas, liquid, or solid as an acoustic wave. Sound is the absorption of such waves and the brain’s perception of them in human physiology and psychology. Sound Vibration A sound’s source vibrates, colliding with surrounding air molecules, which collide with

Introduction The device was used to demonstrate the relationship between the frequency of the sound produced by a plucked string and the tension, length, and mass per unit length of the string. The transverse standing wave of the string produces the sound. The sonometer is made up of a one-meter-long hollow box. A sonometer is

The phenomenon of sound persistence after it has been stopped as a result of many reflections from surfaces such as furniture, people, air, and other objects within a closed surface is known as reverberation. These reflections accumulate with each reflection and progressively fade away as they are absorbed by the surfaces of the objects in

The shift in direction of a wave as it strikes the interface between two materials is known as reflection. The bouncing back of a wave when it strikes an interface between two mediums is known as a reflection of waves. When a wave collides with a surface, a portion of the wave is reflected while

Nodes and antinodes are important in physics. While studying standing sound waves, it is essential to calculate the nodes and antinodes formula. This starts with a detailed understanding of standing sound waves associated with nodes and antinodes. Let us go through the basic behaviour of standing sound waves, nodes, and antinodes. First, we’ll understand the

Standing waves or stationary waves are an important part of physics. The node and antinode of the standing wave give a clear understanding of the amplitude and frequency dynamics during the wave superimposition. Furthermore, the difference between node and antinode gives a clear idea about their specific roles and separates them from the regular crests

When we hear something, it is a type of energy that provides us the feeling of hearing. In the case of a medium (for example, air), it is a form of a mechanical wave that is produced when a source of sound (for example, a tuning fork) begins vibrating in the medium. It is the
