D)sound waves have longer wavelengths than do light waves.
E)interference occurs more readily for longitudinal waves.

Question

Quizplus · Accepted Answer

Diffraction is the bending of waves around obstacles or through openings. This phenomenon is more readily observable in sound waves than in light waves because sound waves are longitudinal, meaning that the particles vibrate back and forth parallel to the direction of wave travel, while light waves are transverse, meaning that the particles vibrate perpendicular to the direction of wave travel. This allows sound waves to bend around corners or through small openings more easily than light waves.
