In my book, it is written that transverse waves are produced during physical motion of tuning fork. But vibration of tuning fork produces sound which are compressional in nature . Please tell me the correct answer and reason behind it.
A tuning fork vibrates like this (in its fundamental mode):
As the tines move sideways they alternately compress and expand the air next to them:
So the sideways motion of the times produces a compression wave in the air.
