Crystal Goblet-Opera Singer Frequency Problem

  1. May 5, 2008 #1
    1. The problem statement, all variables and given/known data

    Standing-wave vibrations are set up in a crystal goblet with four nodes and four antinodes equally spaced around the 15.0 cm circumference of its rim. If transverse waves move around the glass at 920 m/s, an opera singer would have to produce a high harmonic with what frequency to shatter the glass with a resonant vibration?

    2. Relevant equations


    3. The attempt at a solution
    if someone could explain how to do this or do it out it would be good because i have one more chance to get it right otherwise its wrong

    Hi pc21,

    How are the nodes and antinodes related to the wavelength of a wave?
