A. Wavelength contracts so frequency decreases B. Wavelength decreases do amplitude increases C. Wavelength decreases so amplitude decreases D. Wavelength expands so frequency gets lowerHelo, I am having trouble with a homework question. The questionis as follows, "High-frequency sound can be used to produce standing-wave vibrations in a wine glass. A standing-wave vibration in a wine glass is observed to have four nodes and four antinodes equally spaced around the 10.0-cm circumference of the rim of the glass. If transverse waves move around the glass at 923 m/s, an opera singer would have to produce a high harmonic with what frequency to shatter the glass with a resonant vibration as shown in the figure below?". Thanks for the help
