What is a wave in physics?
A wave is a disturbance in a medium that carries energy without a net movement of particles. It may take the form of elastic deformation, a variation of pressure, electric or magnetic intensity, electric potential, or temperature. Table of Content. Introduction of Waves. Types of Waves. Transverse Waves. Longitudinal Wave. Mechanical waves.

- Waves. Wave is a form of disturbance which travels through a material medium due to the repeated f periodic motion of the particles of the medium about their mean positions without any actual.
- Characteristics of wave. The characteristics of waves are as follows: (i) The particles of the medium traversed by a wave execute relatively small vibrations about their mean positions but the particles are not permanently displaced in the direction of propagation of the wave.
- Mechanical waves. Mechanical waves can be produced or propagated only in a material medium. These waves are governed by Newton’s laws of motion. For example, waves on water surface, waves on strings, sound waves etc.
- Electromagnetic Waves. These are the waves which require no material medium for their production and propagation, i.e., they can pass through vacuum and any other material medium.

In the case of a progressive wave, the distance between two points in the same phase at that particular time period is known as the wavelength of a wave. The distance is twice the number of two consecutive nodes and antinodes.
When an element of a medium takes time to move through one complete oscillation then it is called a time period.
In a medium when multiple waves transverse simultaneously, the displacement is the algebraic sum of the displacements due to each wave. This phenomenon is referred to as the principle of superposition.
When two identical waves moving in opposite directions interfere, it results in a standing wave. These waves are characterized by zero displacement locations which are fixed and are called nodes and locations of maximum displacements called antinodes. Related link: Travelling wave
Waves Class 11 CBSE Revision Notes. This article deals with waves class 11 notes. One should wonder what happens in a system that is a collection of objects that oscillate in isolation. A material medium can certainly provide such an example. Furthermore, elastic forces bind constituents to each other.
Mar 16, 2022 · Download PDF. Waves and vibrations are extremely important phenomena, according to Class 11 Physics chapter 15 notes in physics. Oscillations can be found in nature in a variety of ways.
Mar 15, 2021 · Introduction. In this chapter, we shall discuss the type of propagation of waves through different media, and the factors affecting the speed of waves in them. We will also discuss the superposition of waves and Doppler’s effect in sound. Most of us experience the phenomenon of wave propagation when we drop a stone in a pond of still water.
