What is the phase difference between the center of compression and the center of rarefaction in longitudinal wave?
Correct answer: D. 180 deg
- A. 0 deg
- B. 45 deg
- C. 90 deg
- D. 180 deg
Explanation
Option D is correct since the phase difference value ranges from 0 to 2π radians. We know that the phase difference between the two successive compressions of rarefaction is 2π. As rarefaction appears between the two compressions, the phase difference is π, 180 degrees.

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.
