Mathematical Expression for Intensity of Wave Suppose, a progressive wave is travelling along positive x-direction with constant velocity v. Due to wave motion particles of…

Experiment: Proof of the inverse square law When the sound waves originate from a point source, the emitted wave fronts become spherical. If the distance…

Unit of Intensity: According to definition intensity the rate of flow of energy through unit area. So, its S.I. unit is Joule s-1m-2 or, Wm-2…

Dependence of intensity on different factors: Intensity of sound depends on the following factors: Amplitude of vibration of the source: Intensity of sound is proportional…

The intensity of Sound Wave How strong the sound is designated by its loudness. Loudness of a sound is expressed by the intensity of sound.…

Progressive wave Explanation in terms of Wave and Sound We know that when a stone is thrown on a calm water of a pond progressive…

The intensity of wave: The amount of energy transferred per second through unit area normal to the wave is called intensity of the wave. Wave…

Relation among wavelength, frequency and wave velocity Let the velocity of the wave in a medium be v, frequency of the source of the wave…

Wave front: The continuous locus of points having the same phase of vibration in a medium through which a wave propagates is called a wave…

Troughs: In transverse wave, the points where the particles of the medium have maximum displacement in the negative direction are called troughs. The lowest point…
