Which one of the following scenarios accurately describes a condition in which resonance can occur? A. 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. B. 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. C. 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. D. A vibrating tuning fork is struck and begins to vibrate as the object used to strike it is placed away from the tuning fork.
The correct option is B. Resonance is said to occur when one object which is vibrating at the same natural frequency of a second object forces the second object into vibrational motion. When resonance is achieved a big loud voice is usually heard. Resonance generally requires three conditions to occur: 1. An object that has a natural frequency. 2. A force that is functioning at the same frequency as the natural frequency. 3. Prevention of energy loss.
