Answer 1

Explanation:

1.the distance between the same point on two adjacent waves.

2.Sound cannot travel through a perfect vacuum. A vacuum is an area without any air, like space. So sound cannot travel through space because there is no matter for the vibration to work in.

3.We measure sound intensity (also referred to as sound power or sound pressure) in units called decibels.

4.move up and down. In a transverse wave the particle displacement is perpendicular to the direction of wave propagation. ... The particles do not move along with the wave; they simply oscillate up and down about their individual equilibrium positions as the wave passes by.

5.c. spread out in all directions.
