Waves and Sound

We assume that a plane wave travels towards a wall with an opening of size D. Behind the wall, we observe wave within a cone…

A special case of interference applies when a wave interferes with a reflected wave: the two waves are automatically vibrating in phase. We consider the…

In physics, when two sets of waves of the same frequency and same or nearly equal amplitude travelling through the same medium overlap, then it…

We consider a rope [elastic string] and excite it by attaching a vibrator at one end. A transverse wave develops along the wave that is…

We are familiar with waves on water surfaces such as lakes and oceans. We observe crests and troughs travelling towards the beach at a constant…

Stationary wave: When two simple harmonic waves of the same amplitude, frequency and time period travel in opposite direction in a straight line, the resultant…

The wave motion has the following characteristics: The wave motion is periodic vibration which travels through any medium or vacuum. During wave motion, the molecules…

Wave is a form of disturbance which travels through a medium or vacuum and is produced due to periodic motion or vibration of particles about…

Progressive waves transfer energy from one place to another, without transferring the matter. Stationary waves do not transfer energy from one place to another. Besides,…

Conditions of interference of sound are: The two sources should be co-herent i.e. they produce wave-trains of same frequency. The amplitude of the wave-trains must…
