sound in different 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..

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..

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..

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..

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 the properties of the..

The following examples show that sound takes an appreciable time to travel from one place to another. Though lightning and thunder are produced simultaneously, the flash of the lightning is seen much before the sound of the thunder. When a gun is fired at some distance, th..

Refraction of Light - Light not only bounces off surface it goes through some of them often slowing down and changing direction in the process called refraction. It occurs at the point where light travels from one medium to another of different density. Refraction produces mirag..

As seen from equation (1-28), the velocity of sound in a gas depends on g , the ratio of the principle specific heats of the gas. This, in turn, depends on the atomicity of the ga..

As seen from equation (1-28), the velocity of sound in a gas depends on g , the ratio of the principle specific heats of the gas. This, in turn, depends on the atomicity of the gas. An approximate equation connecting g and the degrees of freedom is Where n is the number of degrees of free..
