Solution

  1. Definition of a Wave: A wave is a disturbance that transfers energy from one place to another without transferring matter. It involves the oscillation or vibration of particles in a medium.

  2. Sound as a Wave: Sound is produced by vibrations. These vibrations create sound waves which move through mediums such as air, water, and metal. For example, when a drum is hit, the drum's surface vibrates creating sound waves that travel through the air to our ears.

  3. Energy Transfer: Sound waves carry energy from the source of the sound to the surroundings. For instance, the energy from the vibrating drum surface is transferred to the air particles, which then transfer this energy to our ears, allowing us to hear the sound.

  4. No Transfer of Matter: While sound waves move through a medium, they do not carry the medium with them. For example, when sound travels through air, it does not carry the air particles from the source to the listener. Instead, it's the energy that's transferred through the vibration of the particles.

  5. Conclusion: Therefore, a sound wave is a type of wave because it involves the transfer of energy through the vibration of particles in a medium, without the transfer of matter.
