Answer:

1. The sound waves are longitudinal because particles of the medium through which the sound is transported vibrate parallel to the direction that the sound wave moves.

2. A pulse or a wave is introduced into a slinky when a person holds the first coil and gives it a back-and-forth motion. This creates a disturbance within the medium; this disturbance subsequently travels from coil to coil, transporting energy as it moves.  

Explanation:

answer:

1. longitudinal waves

explanation:

because the vibration of the molelecules occurs in the same direction of propagation of the wave.

answer:

2.  amplitude & frequency

explanation:

large amplitude waves contain more energy.

if more waves pass by, more energy is transferred each second.

hope this helped :) pls give me brainliest <3
