# Resonance in an air column

Before Class Preparation:

• Read this overview of Resonance in an Air Column
• What is the distance between different parts of a standing wave (nodes, anti-node) in terms of wavelength?
• Read this handout: Air Column Resonance
• Print if possible
• Identify the variables on the handout
• We’ll be working with water, so computers are not a good idea

In Class Activity:

• What is the goal in a science experiment?
• Resonance of standing waves
