Final answer:

Striking a metal bar parallel to its length produces transverse waves, while striking it at right angles produces longitudinal waves. Loud sounds don't always break glass because the waves produced may not resonate with the glass object.


Explanation:

When a student strikes a metal bar parallel to its length, transverse waves are produced. When the bar is struck at right angles to its length, longitudinal waves are produced. Glass objects do not break with all loud sounds because the frequency and amplitude of the waves produced may not cause resonance, which is necessary to shatter the glass due to sympathetic vibrations.
