In a standing wave, the number of segments formed is equal to the O number of nodes O number of antinodes O length times wavelength one-half times the length of the vibrating string

A nylon string fixed at both ends vibrates with a fundamental frequency of 196 Hz. Which of the following would have a higher fundamental frequency than this string? An indentical string that is longer. A nylon string with twice the diameter, but the same length. An indentical string that is tightened to a higher tension. An identical string that is given a larger amplitude of vibration.

For a standing wave in an air column in a pipe that is open at both ends, there must be at least:     two antinodes and one node.     one node and one antinode.     two nodes and two antinodes.     two nodes and one antinode.
