sound through a medium

Sound Needs a Medium to Travel - The origin of sound is always some vibrating body. In some cases the vibrations of the source may be very small or very large that it may not be possible to detect them. This type of vibrations is produced by tuning fork, drum, bell, th..

Sound can propagate not only through gases but also through solids and liquids. Some materials like air, water, iron etc can easily transmit sound energy from one place to anothe..

Ordinarily, we hear sound, transmitted through the air. Unlike light, sound cannot pass through vacuum. This was discovered in 1654 by Otto Von Guericke. Let an electric bell be enclosed within a bell jar which is placed over a disc. Through a hole in the disc, air can be remov..

The speed of sound depends on the properties of the medium through which it travel..

Speed of Sound - The flash of lightning due to collision of clouds is seen much before the thunder, although both occur simultaneously. This happens because the velocity of light is greater than the velocity of sound. The speed of sound depends on (1) elasticity and (2..

A material medium is necessary for sound propagation - Ordinarily, we hear sound, transmitted through the air. Unlike light, sound cannot pass through vacuum. This was discovered in 1654 by Otto Von Guericke. Let an electric bell be enclosed within a bell jar..

Sound as a Wave - A ringing bell, a thunderclap, laughter, and rock music are sounds that seem very different to us. However, all sounds are alike because they are waves. Let us understand how wave properties can be applied to sound. Sound is the fo..
