2. select the best definition for a transverse wave: a. particles move at acute angles to the direction of…

Brief Explanations:

In a transverse wave, the particles of the medium move perpendicular (at right - angles) to the direction in which the wave is traveling. Option a is incorrect as acute - angle movement does not define a transverse wave. Option c describes a longitudinal wave where particles move in the same direction as the wave travel.

Answer:

b. particles move at right angles to the direction of wave travel
