Sound

How Does Sound TravelHave you ever thrown pebbles in a pool of water? The impact of pebbles in water creates ripples of waves that spread in the pool. In a similar fashion, vibrations cause waves in the air. We hear the sound when these…

What are the Different Types of SoundSound can be of different types—soft, loud, pleasant, unpleasant, musical, audible (can be heard), inaudible (cannot be heard), etc. Some sounds may fall into more than one category. For instance, the…

Speed Of Sound In Various SubstancesSpeed of Sound: The speed of sound is the rate at which sound travels from the sound producing body of our ears. The speed of sound depends on theNature of Material: (or medium) through which it travels.…

Reflection Of SoundSound waves like light waves also get reflected from plane and spherical surfaces. During reflection, sound waves obey the laws of reflections. The reflection of sound from a hard surface can be observed by performing a…

What Is EchoThe sound returning back towards the source after suffering reflection from a distance obstacle (a wall, a row of building etc.) is called an echo.When the sound is reflected repeatedly from a number of obstacles, more than one…

Classification Of Wave MotionOn the Bases of Necessity of Medium RequiredMECHANICAL WAVES The wave which propagates only in a material medium are called elastic or mechanical waves. Example: Sound waves, Water waves (ripples), Waves on…

Analysing Sound WavesSounds are mechanical waves. They are caused by vibrating objects. The string of a guitar, the skin of a drum and a tuning fork, all of these vibrate to produce sound. The vibrating cone of a loudspeaker in Figure…
