What is the speed at which sound travels in glass

The speed of sound propagation in the air is equivalent to 3/5 of the speed of propagation in glass, and the speed of sound propagation in glass is 550 (m s).

Sound is a sound wave produced by the vibration of an object. It is a wave phenomenon that propagates through a medium (air or solid, liquid) and can be perceived by the auditory organs of humans or animals. An object that initially emits vibrations (vibrations) is called a sound source.

Sound travels in the form of waves that vibrate (vibrate). Sound is the motion formed by the propagation of sound waves through any substance.

Sound is a wave, and the sound with a frequency between 20 Hz and 20 kHz can be recognized by the human ear.

The propagation of sound requires a medium, which can propagate in both gases and solids and liquids. (but not in a vacuum).

When the house is closed, the outside world is quiet. It is because we prevent it by the propagation of sound (noise). (Because solid can also transmit sound, "the outside sound is small", if it is a soundproof door, a soundproof wall is a different matter).

1. Kaixiang refractive index definition.

The formula formulation: n=sin sin, let's review the definition of refractive index:

When light is refracted from a vacuum into a medium, the ratio of the sine of the angle of incidence to the sine value of the angle of refraction is a fixed value, which is called the "absolute refractive index" of the medium in the state, or "refractive index" for short.

The refractive index is denoted by the symbol n. i.e. n=sin sin; where is the angle of incidence when light is refracted from a vacuum into the medium, which is the angle of refraction. It should be noted that it is always greater than , so the refractive index n is always greater than 1.

2. Supplementary formula for refractive index.

1、n=c/v；

C refers to the velocity of light in a vacuum, and V refers to the velocity of light in that medium.

2、n=1/sinc；

c refers to the critical angle of the medium.

The propagation speed of sound in a certain glass is 15 times that of air, and the speed of sound propagation in this glass is.

v=15x340=5100m/s

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 Cha or S

Kerosene (25) 1324m s

Distilled water (25) orange lift 1497ms

Seawater (25) 1531m s

Copper (rod) 3750m s

Marble 3810m s

Aluminum (rod) 5000m s

Iron (rod) 5200m defeated Wu S

Sound travels at different speeds in different substances. I just didn't find the glass, so look for it again.

The propagation speed of sound in the glass of a certain limb nucleus is 15 times that of the air hunger, and the propagation speed of sound in this glass is based on the base of the excavation.
