Answer: B
Explanation:
Dispersion refers to the phenomenon where different components of a wave, such as different frequencies or wavelengths, travel at different speeds through a medium. This causes the wave to separate or spread out. Dispersion commonly occurs in materials like prisms, where white light is separated into its component colors.
Sound waves, on the other hand, are mechanical waves that propagate through a medium by compressions and rarefactions of particles. While sound waves can undergo diffraction (bending around obstacles), reflection (bouncing off a surface), and refraction (changing direction when passing from one medium to another of different density), they do not exhibit dispersion.
