Evaluate frequency to shatter the glass with a resonant vibration? Standing-wave vibrations are set up in a crystal goblet with four nodes and four antinodes equally spaced around the 10.0 cm circumference of its rim. If transverse waves move around the glass at 940m/s, an opera singer would have to produce a high harmonic with what frequency to shatter the glass with a resonant vibration?
