What type of wave is produced when a tuning fork is struck?

Step 1: Understand what a tuning fork is. It is a metal instrument that produces sound when struck.
Step 2: When the tuning fork is struck, it vibrates. This means it moves back and forth quickly.
Step 3: As the tuning fork vibrates, it pushes the air particles around it.
Step 4: This pushing creates areas where air particles are close together (compressions) and areas where they are spread apart (rarefactions).
Step 5: The movement of these compressions and rarefactions travels through the air as a wave.
Step 6: The type of wave created by this movement is called a longitudinal wave.
