Which factors affect the speed of a wave in a medium?

The speed of a wave in a medium is primarily influenced by the medium's density, elasticity, and temperature.

Density refers to how much mass is contained in a given volume of the medium. Generally, in a homogeneous medium, the greater the density, the slower the wave travels when other conditions are constant. However, for various types of waves, such as sound waves, a denser medium can actually lead to faster wave propagation if the elasticity is also high.

Elasticity is a measure of how easily the medium can return to its original shape after being disturbed. A medium with high elasticity can transmit waves faster because the particles can easily spring back to their initial positions, allowing energy to transfer quickly.

Temperature affects the particles in a medium. As temperature increases, particles typically move faster, allowing waves to travel more rapidly. For example, sound waves travel faster in warmer air than in cooler air because the increased energy of the molecules facilitates faster propagation of sound.

The other options, while they may have some considerations regarding wave behavior, do not accurately encompass the fundamental physical properties that influence the speed of waves in different media. Factors like color, shape, weight, and sound levels do not provide relevant insights into the mechanics of wave propagation. Only the properties of
