Waves and Sound

When two progressive waves of same amplitude and wavelength travelling along a straight line in opposite directions superimpose on each other, stationary waves are formed.…

In musical instruments like sitar, violin, etc. sound is produced due to the vibrations of the stretched strings. Here, we shall discuss the different modes…

Uses of beats: (i) The phenomenon of beats is useful in tuning two vibrating bodies in unison. For example, a sonometer wire can be tuned…

When two waves of nearly equal frequencies traveling in a medium along the same direction superimpose upon each other, beats are produced. The amptitude of…

Demonstration of Interference of Sound: The phenomenon of interference between two longitudinal waves in air can be demonstrated by Quincke’s tube shown in Figure. Quincke’s…

When two waves travel in a medium simultaneously in such a way that each wave represents its separate motion, then the resultant displacement at any…

Difference between longitudinal and transverse wave is: Longitudinal Wave When the motion the particles of the medium are parallel to the direction of propagation of…

A progressive wave is defined as the forward transmission of the vibratory motion of a body in an elastic intermediate from one element to the successive…

The incident and reflected ray obey two simple laws: First law: The incident ray, reflected ray and the normal at the point of incidence on…

We know, light is a form of energy by which we are able to see the objects. When light comes from an object to our…
