Which one is not produced by sound wave in air?
Correct answer: A. Polarization
- A. Polarization
- B. Diffraction
- C. Refraction
- D. Reflection
Explanation
Polarization is a phenomenon associated with transverse waves, where the vibrations occur perpendicular to the direction of wave propagation. Sound waves are longitudinal waves, meaning the vibrations are along the same direction as the wave's propagation. Therefore, sound waves in the air do not exhibit polarization.

About Waves
Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fλ; sound speed depends on the medium. Superposition produces interference and stationary waves in strings and organ pipes, while simple harmonic motion describes the oscillation itself and must be distinguished from wave propagation.
