Questions & Step-by-Step Solutions

What is the frequency of a wave with a period of 0.2 seconds?
  • Step 1: Understand that frequency (f) is how many times something happens in one second.
  • Step 2: Know that the period (T) is the time it takes for one complete cycle of the wave.
  • Step 3: The relationship between frequency and period is given by the formula: f = 1/T.
  • Step 4: Substitute the period value into the formula. Here, T = 0.2 seconds.
  • Step 5: Calculate the frequency: f = 1/0.2.
  • Step 6: Perform the division: 1 divided by 0.2 equals 5.
  • Step 7: Conclude that the frequency of the wave is 5 Hz.
