Follow @physics_unplugged | video description 👇 The speed of sound describes how fast vibrations travel through a medium. At 20°C or 68°F, the speed of sound in air is approximately 343 m/s (1,235 km/h). This results in about 2.91 seconds to cover a kilometer and 4.69 seconds to travel a mile. Curiously enough, in warmer air, sound moves faster because the particles move more easily. Comparatively speaking, sound in water travels at a speed of about 1,480 m/s-more than four times as fast as in

The speed of sound and the speed of light are two fundamentally different quantities with significantly different values. The speed of sound refers to the velocity at which sound waves propagate through a medium, such as air, water, or solids. The speed of sound is dependent on the properties of the medium, such as density and elasticity. In dry air at sea level and at a temperature of about 20 degrees Celsius, the speed of sound is approximately 343 meters per second or 1,125 feet per second. #
