Which one of the following scenarios accurately describes a condition in which resonance can occur? A. A column of air has a hei
ght 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 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 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.
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.
Explanation:
Resonance happens when the amplitude of an object's vibrations are enhanced by the parallel vibrations of a different object. Resonance is the tendency of a mode to vibrate with raising amplitudes at some wavelengths of excitation. These are identified as the system's loud frequencies. The resonator may have a primary frequency and any number of harmonics.
Once the Earth was full of water (ocean) after volcanic activities the mainland became land ( sorry about my english i am hungarian and i am still learning the language )
