Tuning
forks make a sound when they are hit. Use a mallet to hit a tuning
fork, and then touch the end of the tuning fork against the tip
of your finger.
What if you don't have a tuning fork? OK- then you
can try it with a metal tube. You need to be careful not to hit it
so hard that you injure yourself!
Safety concerns:
Be sure to keep all Eye Safety Rules that are specified by your teacher
and in all general laboratory experiences.
