What is the trend of the speed of sound and the rigidity of solids?
The speed of sound in a solid material is directly related to the rigidity of the material. As the rigidity of a solid increases, the speed of sound also tends to increase. This is because sound waves travel faster through materials that are more rigid and have higher elastic moduli.
In general, the trend for the speed of sound and the rigidity of solids is that they are positively correlated. This means that as the rigidity of a solid material increases, the speed of sound through that material also increases. Different materials will have different speeds of sound and rigidity values, but the overall trend remains the same.
