Longitudinal waves do not exhibit _____________________?
Correct answer: D. polarization
- A. reflection
- B. refraction
- C. diffraction
- D. polarization
Explanation
Polarization requires vibrations to be restricted to one direction perpendicular to propagation, which is possible for transverse waves but not for longitudinal waves. Option c is a common mistake because longitudinal waves can diffract when their wavelength is comparable with an opening or obstacle.

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.
