RossElasticity directly affects the speed of sound. In general, the speed of sound is faster in materials with higher elasticity. This is because the quicker the material can return to its original shape after being compressed or stretched, the faster sound waves can propagate through it.
The speed of any wave depends upon the properties of the medium through which the wave is traveling. Typically there are two essential types of properties that effect wave speed - inertial properties and elastic properties.
For virtually all forms of sound, the speed of sound is proportional to the square root of the ratio of the elasticity to the density. Or, velocity squared equals elasticity divided by density.

Elastic properties are those properties related to the tendency of a material to maintain its shape and not deform whenever a force or stress is applied to it. A material such as steel will experience a very small deformation of shape (and dimension) when a stress is applied to it. Steel is a rigid material with a high elasticity. On the other hand, a material such as a rubber band is highly flexible; when a force is applied to stretch the rubber band, it deforms or changes its shape readily. A small stress on the rubber band causes a large deformation. Steel is considered to be a stiff or rigid material, whereas a rubber band is considered a flexible material. At the particle level, a stiff or rigid material is characterized by atoms and/or molecules with strong attractions for each other. When a force is applied in an attempt to stretch or deform the material, its strong particle interactions prevent this deformation and help the material maintain its shape. Rigid materials such as steel are considered to have a high elasticity. (Elastic modulus is the technical term). The phase of matter has a tremendous impact upon the elastic properties of the medium. In general, solids have the strongest interactions between particles, followed by liquids and then gases. For this reason, longitudinal sound waves travel faster in solids than they do in liquids than they do in gases. Even though the inertial factor may favor gases, the elastic factor has a greater influence on the speed (v) of a wave, thus yielding this general pattern:
vsolids > vliquids > vgases

How elasticity of a medium affects the speed at which sound travels?
by causeing larger sound waves through objects
How does the speed of sound relate to temperature elasticity and density?
The speed of any mechanical wave depends on the density of the medium. Since solids are the densest, the speed of sound is minimum in solids. It is the maximum in gases, since the medium is the least densest.
What two factors effect the speed of sound?
The two main factors that affect the speed of sound in a material are the density of the material and the elasticity of the material. In general, sound travels faster in materials that are more dense and have higher elasticity.
What does the speed of sound measure?
The speed of sound measures how fast sound waves can travel through a medium, such as air, water, or solids. It is influenced by factors like temperature, density, and elasticity of the medium.
When is speed of sound the greatest?
The speed of sound is greatest in solids, as the particles are closer together and can transmit vibrations faster. In general, the speed of sound increases with an increase in density and elasticity of the medium.
