We hope this detailed article on Standing Waves will be helpful to you in your preparation. Do energy and momentum are transferred in a standing wave?Īns: No, energy and momentum are not transferred in a standing wave. Antinodes are points with the greatest amplitude. Hear the sound produced by the speaker, and discover what determines the color of light. Beats are formed by the interference of incoherent waves.Īns: Nodes are the point in a standing wave whose amplitude is zero. Make waves with a dripping faucet, audio speaker, or laser Adjust frequency and amplitude, and observe the effects. On a string, it is formed y superposition of the incident and the reflected wave.Īns: No, beats are not standing waves. Example: Light waves are generated from the sun, and they get transferred to the earth.Īns: Standing waves are formed by the interference of coherent waves. Thus, the amplitude of the resultant will be a function of the position of the point.Īns: Waves are a phenomenon that propagates from one place to another and transfers energy and momentum. Let the velocity of the wave in the medium be u then the time take for this disturbance to travel a distance \(x\) is, \(t = \,\frac \right)\) The equation of the disturbance is that of an SHM, i.e., Hamonic wave is produced by a disturbance that is under simple harmonic motion. The frequency, wavelength, and the wave velocity are related as,įrequency is the inverse of the time period. Wavelength: It is the distance after which the wave repeats itself. Phase: It is the state of the particle when the wave is passing through it. Time-period: It is the time interval after which the wave repeats itself. In simple words, if we chose any position, then the wave will be periodic with time at that position and repeat itself after a fixed interval of time, and if we freeze time and move in space, then the wave will be periodic in space and repeat itself after a fixed distance. That is, the wave is periodic in time and periodic in space as well. The disturbance performs the simple harmonic motion.The properties of harmonic waves are as follows: Harmonic wave: Waves that have the sinusoidal equation are known as harmonic waves.
