sound can propagate in vacuum?

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 ..

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 ca..

Sound is the form of energy propagated as waves which our ears receive. When we speak, our vocal cords vibrate. When we play a guitar, the spring on it makes to and fro motion and produces sound..

Sound is always produced due to the vibration of a 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, the string of a guitar etc. Human voice originate..

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..

A wave motion, in which the particles of the medium oscillate about their mean positions in the direction of propagation of the wave, is called longitudinal wave. Sound waves are classified as longitudinal waves. Let us now see how sound waves propagate. Tak..

Introduction - You have learnt that sound is a form of energy. It is produced by vibrations. Sound waves are longitudinal waves. They are also elastic waves hence they need a material medium for their transmission. They can not be transmitted in vacuum. They travel in ..
