What is the frequency of a tuning fork that vibrates 256 times in 2 seconds? (2019)
  • Step 1: Identify the number of vibrations. In this case, the tuning fork vibrates 256 times.
  • Step 2: Identify the time period over which the vibrations occur. Here, the time is 2 seconds.
  • Step 3: Use the formula for frequency, which is Frequency (f) = Number of vibrations / Time.
  • Step 4: Plug in the values: f = 256 vibrations / 2 seconds.
  • Step 5: Calculate the frequency: 256 divided by 2 equals 128.
  • Step 6: State the final answer: The frequency of the tuning fork is 128 Hz.
