The speed of sound depends on several variables, but the only independent variable we need to calculate the speed of sound is the temperature of the air. Enter your air temp and choose your units: The speed of sound: mph. Fahrenheit.
Web8 jul. 2024 · You may recall from your high school science classes that of the three states of matter, i.e., solid, liquid and gas, sound waves travel the fastest through solids. The second best is liquid, meaning that sound travels the slowest through gases. What this means is that if you want sound to travel from one place to another, you should try to … WebWe can find the speed of sound by looking at the speed of this compressed region as it travels through the medium.
