How fast does sound travel? 20

The propagation of sound requires matter, which is called a medium in physics.

The speed at which sound travels in different media:

Vacuum 0m s (i.e. no propagation).

Air (15) 340m s

Air(25) 346m s

Cork 500m s

Kerosene (25) 1324m s

Distilled water (25) 1497 ms

Seawater (25) 1531m s

Copper (rod) 3750m s

Marble 3810m s

Aluminum (rod) 5000m s

Iron (rod) 5200m s

The propagation velocity is different in different media. Generally, it is 340ms at room temperature of 15 degrees Celsius

Sound is a sound wave produced by the vibration of an object. It is a wave phenomenon that is transmitted through a medium and can be perceived by the auditory organs of humans or animals. The speed at which sound travels in different mediums is different.

In general, sound travels faster in solids than in liquids, and faster in liquids than in air.

The propagation of sound requires matter, and in physics, such a substance is called a medium, which can be air, water, or solid, of course, in a vacuum, sound cannot be propagated, and the propagation of sound is related to temperature and resistance.

The speed at which sound travels in different media is not the same:

At air 15, the propagation velocity is 340m s.

At air 25, the propagation velocity is 346m s.

In water at room temperature, the propagation velocity is 1500m s.

At seawater 25, the propagation velocity is 1530m s.

In steel, the propagation velocity is 5200m s.

In ice, the propagation velocity is 3160m s.

In cork, the propagation velocity is 500 m s.

In pine, the propagation velocity is 3320 m s.

In nylon, the propagation velocity is 2600m s.

In cement, the propagation velocity is 4800m s

1. The propagation speed of sound in the air is: air (15) 340m s, air (25) 346m s.

2. Different water propagation velocities are different, distilled water (25) 1497m s, seawater (25) 1531m s. Copper (rod) 3750m s, aluminum (rod) 5000m s, iron 5200m s.

3. Sound varies according to the speed of propagation in different substances. The propagation of sound is also related to temperature and resistance, as well as different densities. It affects the speed at which sound travels.

The propagation of sound requires a mediumThe propagation of sound requires a medium, usually the speed of sound refers to the speed of sound in the air, and the speed of sound will have different values depending on the state of the air.

For example, the speed of sound at sea level at zero degrees Celsius is about 295 m s at an altitude of 10,000 meters, and the speed of sound increases for every 1 degree Celsius increase.

Hello dear! The propagation velocity scattering band stun is a physical quantity used to express the propagation speed of a wave, which represents the ratio of the displacement vector of a given property of a field in a specified time interval to the duration of the punching time interval at a given moment and a point in a given space, and the limit when the duration approaches zero.
