PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

Answer 1

Answer: Up and down

Explanation :

The waves that require a medium to travel through are mechanical waves. There are two types of mechanical waves.

1. Longitudinal waves
2. Transverse waves

The given figure shows a transverse wave in which the particles of the medium move up and down to the direction of propagation of waves i.e. the medium particles are perpendicular in the direction of motion of waves.

The uppermost portion of waves is called crest while the lowermost portion is a trough.

Hence, the correct option is (C).

Answer 2

Up and down, diagonally, anything that's ACROSS the direction the wave is moving.  

Just NOT back and forth along the line the wave is moving.
