The speed of sound waves depends on the medium through which they travel. In general, sound waves travel faster in denser and more elastic mediums. Here are some approximate speeds of sound in different materials at room temperature (around 20 degrees Celsius or 68 degrees Fahrenheit):
In air: The speed of sound in dry air at sea level is about 343 meters per second (1,125 feet per second) or roughly 1235 kilometers per hour (767 miles per hour).
In water: Sound travels faster in water than in air. The speed of sound in freshwater at around 20 degrees Celsius is about 1,484 meters per second (4,872 feet per second) or approximately 5,342 kilometers per hour (3,320 miles per hour).
In steel: Sound waves travel even faster in solids. In steel, the speed of sound is approximately 5,960 meters per second (19,550 feet per second) or roughly 21,456 kilometers per hour (13,344 miles per hour).
It's important to note that these values are approximate and can vary depending on factors such as temperature, humidity, and pressure. Additionally, the speed of sound can vary in different materials or substances.
