Sound in physics is defined as how a wave is automated or mechanically transmitted and its frequencies. It can move in several different circles in its three solids, liquid. Gaseous situations. So we conclude that it cannot move through an open center. The speed of sound is estimated at 343 meters per second within the center of a dry antenna at a temperature of up to twenty Fahrenheit.

Sound Wave Properties

Sound waves are a type of energy transformation from one form to another. It is converted from sound waves to electrical signals through the ear to become understandable information transmitted to the brain. The latter translates it and understands it.

Sound Wave Classification

Audible waves: human audible waves, ranging in 20 to 20,000 hertz, i.e., between the minimum and highest frequency of human sound. Ultrasound: waves that exceed 20,000 hertz, i.e., fall outside the human hearing and are used in several areas, including medicine and industry.

Subsonic waves: waves whose frequency decreases below 20 hertz and cannot be heard or felt as earthquakes and volcanoes, while some animals can sense them before they occur.

The speed of sound for its transmission depends on the type of medium in which it spreads and on the temperature; the sound is higher in solids, lower in liquid circles, and much lower in the gas community. But concerning temperature. The relationship between it and the speed of sound is ejected as the temperature rises.

Still, it spread in the air depends on pressure, i.e., the rate of sound decreases by rising above the ground.

Volume physicists have adopted a dimple unit to measure its intensity of it. Sometimes called a disabled watt, which is the best measure of this matter.

Where the decibel is built on the forces of number ten (10). And the decibel is (10)-2) watts/square meters. The sound travels in longitudinal waves amid gases, fluids, and plasma. In contrast, it takes the form of longitudinal and transverse waves together during propagation for solid circles.

Sound Speed in Solid Objects

It travels between solid particles that are more interconnected than in liquids and gases. Where the density of solids is significant. Resulting in particles colliding with each other more quickly. These molecules take less time to collide with each other. Making it more excellent than the gas or liquid medium.

For example, its velocity in a solid-state is about 6,000 m/s. Still, in steel, it is 5,100 m/s, i.e., the speed of transmission in solids is very high. And the information of it in the diamond element is about 35 times faster than in the air.

Fluid Sound

It is transmitted in liquids that are denser than gases but less dense than solids, i.e., the distances between their molecules are lower than those in gases. While they are more than solids, so the speed of it in liquids is between the speed of it in solid and gaseous circles

Gas Sound

It travels through gases slowly because the particles that make up the gas material diverge and spread so that until the sound travels through the gas. The particles must vibrate and collide with each other to form sound waves.

But because of the large spacing of matter molecules in gases. The process of energy transmission from one molecule to another takes longer compared to solids and liquids. So its speed of it is lower in the gaseous state.

Speed of it in gases does not consider the type of medium due to the density of the standardized gases of any kind.
