Question

Fine sand particles are placed on a on a paper plate and the plate is set on top of a stereo speaker. The stereo is turned on and the music is played very loudly. The sand particles on the plate bounce around and arrange themselves in different patterns. What causes the formation of these patterns?

Answer 1

Answer:

These patterns are caused by the vibrations of sound waves.

Explanation:

Sound waves are vibrations that, when penetrating our ear, produce auditory sensations. Sound waves are a physical phenomenon and their vibrations have the power to cause physical reactions that can be seen with the naked eye, as is the case shown in the question above, where through the vibration the sand particles on the plate on top of a box sound oscillate and organize in different patterns.

Sound waves play a very important role in our daily lives and have characteristics that can help us constantly.

Answer 2

The vibrations of the music coming from the speaker makes the sand move.
