Item RG194001: As sound from a speaker travels through water, the matter moves back and forth in a wavelike motion.
A man puts a speaker next to a container of liquid. The speaker makes a continuous sound that travels through the liquid.
What happens to the matter at point X inside the container while the sound travels through the liquid?
- As sound travels through the liquid, the matter at point X moves in the direction of the sound and travels toward the other side of the container.
- As sound travels through the liquid, the matter at point X moves back and forth in a wavelike motion.
- If the liquid is thick, like honey, the matter at point X will not move when sound travels through it, but if the liquid is thin like water, the matter at point X will move with the sound.
- Nothing happens to the matter at point X. Matter is not disturbed when sound travels through a liquid.
