d) do not vibrate​

Answer 1

c)vibrate perpendicular to the direction of the wave motion

Answer 2

Answer:

Option c is the correct answer.

Sound vibrations, then, travel outwards in all directions in waves from a sound source. As they travel outwards the energy they contain becomes dissipated and therefore the sound becomes weaker the further it is from the source.
