Question

A tuning fork of frequency 256 Hz will resonate with another tuning fork of frequency:

• A. 128 Hz
  
• B. 256 Hz
  
• C. 384 Hz
  
  
• D. 500 Hz

Answer 1

The correct option is B

256 Hz

The vibrations of a body under an external periodic force of frequency exactly equal to the natural frequency of the body, are called the resonant vibrations. Hence, a tuning fork of frequency 256 Hz will resonate with another tuning fork of same natural frequency, which is 256 Hz.
