Question

the type of wave that eli creates in the spring toy is called a longitudinal wave.

unlike a transverse wave, a longitudinal wave travels in a direction that is parallel to the direction the particles in the medium move. when eli moves his hand back and forth, the coils in the spring toy squeeze together and pull apart horizontally. a wave of compressing and stretching then travels along the horizontal length of the spring toy.

complete the sentences.

the longitudinal wave that eli creates in the spring toy travels from left to right and the particles in the spring move. this means that the wave and the particles of matter move in

Explanation:

According to the text, a longitudinal wave travels in a direction parallel to the direction the particles in the medium move. Since the wave travels from left to right, the particles must also move left and right (parallel direction).

Answer:

The particles in the spring move left and right. This means that the wave and the particles of matter move in the same direction (parallel).
