When a guitar string is struck, a standing wave is produced that oscillates with a large sustained amplitude, pushing back and forth against the surrounding air to generate sound. How does the frequency of the resulting sound compare with the frequency of the standing wave in the string? 1. The frequencies of the resulting sound have nothing to do with those of the standing wave in the string. 2. The frequencies of the resulting sound are half of those of the standing wave in the string. 3. The frequencies of the sound and the oscillating string are the same. 4. The frequencies of the resulting sound are twice of those of the standing wave in the string.4
