The speed of sound waves depends on the medium through which they are traveling. In general, sound travels fastest through solids, slower through liquids, and slowest through gases.
In dry air at sea level and at a temperature of around 20 degrees Celsius (68 degrees Fahrenheit), the speed of sound is approximately 343 meters per second, which is equivalent to about 1,125 feet per second or 767 miles per hour.
However, the speed of sound is not a fixed value and can vary based on factors such as temperature, humidity, and the composition of the medium. In general, sound waves travel faster in warmer air and slower in colder air. The density and elasticity of the medium also affect the speed of sound.
For example, in water, sound travels at a speed of about 1,482 meters per second (4,875 feet per second), which is roughly four times faster than in air. In solids, such as steel or rock, sound can travel even faster, often reaching speeds of several kilometers per second.
It's worth noting that the given values are approximate and can vary based on the specific conditions and properties of the medium.
