What is a transverse wave?

• A wave that moves the medium in the same direction as the wave travels

• A wave that moves the medium in a direction perpendicular to the direction in which the wave travels

• A wave that does not move the medium

• A wave that moves in a circular motion

What is a longitudinal wave?

• A wave in which the disturbance is perpendicular to the direction the wave travels

• A wave in which the disturbance is random to the direction the wave travels

• A wave in which the disturbance is parallel to the direction the wave travels

• A wave that does not require a medium to travel
