Step 1: Understand the concept of dispersion. Dispersion occurs when waves of different frequencies travel at different velocities in a medium.
Step 2: Examine transverse waves. In transverse waves, such as light waves, the speed can vary with frequency in a medium leading to dispersion (e.g., the separation of colors in a prism).
Step 3: Examine longitudinal waves. Longitudinal waves, like sound waves, can also exhibit dispersion. In certain media, different frequencies of sound can travel at different speeds, causing dispersion.
Conclusion: Therefore, both transverse and longitudinal waves can experience dispersion.
