Questions & Step-by-Step Solutions

What is the time period of a wave with a frequency of 20 Hz? (2022)
  • Step 1: Understand that frequency (f) is how many times a wave repeats in one second. In this case, the frequency is given as 20 Hz.
  • Step 2: Know that the time period (T) is the time it takes for one complete wave to pass a point. It is the opposite of frequency.
  • Step 3: Use the formula for time period, which is T = 1/f.
  • Step 4: Substitute the frequency value into the formula. Here, f = 20 Hz, so T = 1/20.
  • Step 5: Calculate the result. 1 divided by 20 equals 0.05.
  • Step 6: Conclude that the time period of the wave is 0.05 seconds.
