Questions & Step-by-Step Solutions

A tuning fork produces a sound wave of frequency 440 Hz. What is the period of the wave? (2019)
  • Step 1: Understand that frequency (f) is the number of waves that pass a point in one second, measured in Hertz (Hz).
  • Step 2: Know that the period (T) is the time it takes for one complete wave to pass a point, measured in seconds (s).
  • Step 3: Use the formula to find the period: T = 1/f.
  • Step 4: Substitute the frequency into the formula: T = 1/440 Hz.
  • Step 5: Calculate the period: T = 1/440, which is approximately 0.00227 seconds.
  • Wave Properties – Understanding the relationship between frequency and period of a wave, where the period is the reciprocal of frequency.
