Explanation:

I took the test & made an 100%. Also, good luck w/ High School & your final year in school and hopefully college! Wish you the best.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.
