Question

can we always see the vibrations? answer pleasee​

Answer 1

Since air is invisible to begin with, there's no way for you to see the air once it starts vibrating. ... The vibrating motion of most sound waves is far faster than your waving hand, and is therefore just a blur to human eyes. The sound waves traveling down a plucked guitar string are not invisible.

Answer 2

Answer:

Mostly, a sound-producing object vibrates at a faster rate that we cannot see its vibrations with our naked eyes. The time interval between two successive vibrations is less than the persistence of vision.
