Answer:
It depicts a transverse wave.
Step-by-step explanation:
The illustration depicts a transverse wave.
Transverse wave is the type of mechanical wave that occurs when the vibration of the medium is perpendicular to the direction of the wave produced by the medium.
Given the red dots to be the vibration of the medium and the blue dots to be the direction of the wave, since the vibration is in the vertical direction and the blue dots are moving in the horizontal direction, this shows that they are perpendicular to each other thereby depicting a transverse wave.
