Question

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 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. 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 vibrating tuning fork is struck and begins to vibrate as the object used to strike it is placed away from the tuning fork.

Answer 1

The correct option is D.
Resonance refers to a phenomenon in which a vibrating system drives another system to oscillate with greater amplitude at specific frequencies. Resonance occurs because the vibrating system is able to store energy and also transfer it between two or more storage modes. The phenomenon of resonance occur in all types of waves.

Answer 2

In physics, resonance is a phenomenon in which a vibrating system or external force drives another system to oscillate with greater amplitude at specific frequencies. Frequencies at which the response amplitude is a relative maximum are known as the system's resonant frequencies or resonancefrequencies.

The answer is 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.
