For a transverse wave, the particle displacement is oriented relative to the direction of propagation as?

• A. Perpendicular
• B. Parallel
• C. Circular
• D. Diagonal

Answer: (A)

In a transverse wave, the medium’s particles oscillate perpendicular to the direction the wave travels. If the wave moves to the right, the particles move up and down. This perpendicular relationship is what defines a transverse wave, in contrast to longitudinal waves where the displacement is along the direction of travel (compressions and rarefactions). Diagonal or circular displacements would imply components along the propagation direction or a circular motion, which are not the standard orientation for a simple transverse wave.
