Classroom Ideas

What stops the glass from breaking? Why does the experiment require a frequency similar to the natural frequency of the glass? What would happen if a different frequency was used? Encourage students to investigate and share their answers with the class. Use a signal generator and oscilloscope to carry out practical work to reinforce the ideas covered.
