Question

Which one of the following scenarios accurately describes a condition in which resonance can occur? A. 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. B. A vibrating tuning fork is struck and begins to vibrate as the object used to strike it is placed away from the tuning fork. C. 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. 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.

Answer 1

The correct option is A.
Resonance is the phenomenon by which a vibrating system or an external force drives another system to oscillate with greater frequencies at specific frequencies. These specific frequencies are called resonant frequencies. At resonance frequencies, small periodic driving forces have capacity to produce large amplitude oscillation.

Answer 2

Answer:

The answer is option A.

Explanation:

Reverberation is the wonder by which a vibrating framework or an outside power drives another framework to waver with greater frequencies at particular frequencies. These particular frequencies are called thunderous frequencies. At reverberation frequencies, little intermittent main impetuses have ability to create vast sufficiency swaying.
