What does the baseball bat oscillate like this? When a baseball strikes a bat, it can cause the bat to vibrate at its natural frequencies, producing resonance, which is when an object vibrates with a larger amplitude because the driving force matches its natural frequency. These vibrations form standing waves along the length of the bat, with specific points that hardly move called nodes and points that oscillate the most called antinodes. The position of these nodes and antinodes depends on the
