Question: If a wave has a frequency of 50 Hz, what is its period? (2022)

Options:

  1. 0.02 s
  2. 0.5 s
  3. 2 s
  4. 20 s

Correct Answer: 0.02 s

Solution: 

Period (T) = 1/Frequency = 1/50 Hz = 0.02 s.

Questions & Step-by-Step Solutions

If a wave has a frequency of 50 Hz, what is its period? (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 50 Hz.
  • Step 2: Know that the period (T) is the time it takes for one complete wave cycle to pass a point. It is the inverse of frequency.
  • Step 3: Use the formula for period: T = 1/Frequency.
  • Step 4: Substitute the frequency value into the formula: T = 1/50 Hz.
  • Step 5: Calculate the result: T = 0.02 seconds.
  • Wave Properties – Understanding the relationship between frequency and period, where period is the reciprocal of frequency.
