Which one of the following scenarios accurately describes a condition in which resonance can occur? a. a vibrating tuning fork is struck and begins to vibrate as the object used to strike it is placed away from the tuning fork. b. a column of air has a height equal to 1⁄8 of the wavelength of the sound waves produced by a tuning fork vibrating over the column of air in an open pipe that's partially immersed in water. c. a pipe's length is equal to 1⁄2 of the wavelength of the sound waves produced by a tuning fork vibrating over one end of the pipe that's open to the air at both ends. d. a person is holding a tuning fork on one end of a football field and another person is holding a separate tuning fork on the opposite end of the field.
