Correct answer: C. Longitudinal waves

  • A. Matter waves
  • B. Transverse waves
  • C. Longitudinal waves
  • D. Electromagnetic waves

Explanation

Sound waves are a classic example of longitudinal waves. In longitudinal waves, the displacement of the medium is parallel to the direction of wave propagation. This is different from transverse waves, where the displacement is perpendicular to the direction of propagation. Matter waves are related to quantum mechanics and are not a good description of sound. Electromagnetic waves, such as light, are transverse and do not require a medium to travel, unlike sound waves, which need a medium like air or water.

About Progressive Waves

Progressive waves transfer energy through a medium or space while particles oscillate about their equilibrium positions. The work includes amplitude, wavelength, frequency, period, phase difference, wave speed and the progressive wave equation, while distinguishing travelling waves from stationary waves, where the pattern has fixed nodes and antinodes.
