Speeds in Different MediumsElastic properties and inertial properties can affect the speed. Elastic properties are those properties related to the tendency of a material to maintain its shape and not deform when a force or stress is applied to it, like steel, and inertial properties are those properties related to the material’s tendency to be sluggish to changes in its state of motion, and the density of a medium is an example of an inertial property. The speed of a sound wave in the air depends on the properties of the air, such as temperature and humidity.
