What is the frequency of a wave if its period is 0.02 seconds?
Correct Answer: 50 Hz
Step 1: Understand the terms. The 'period' (T) is the time it takes for one complete wave to pass a point. The 'frequency' (f) is how many waves pass that point in one second.
Step 2: Know the formula. The frequency is calculated using the formula f = 1/T.
Step 3: Identify the period. In this case, the period (T) is given as 0.02 seconds.
Step 4: Plug the period into the formula. Replace T in the formula with 0.02 seconds: f = 1/0.02.
Step 5: Calculate the frequency. Divide 1 by 0.02 to get the frequency: f = 50 Hz.
Step 6: State the answer. The frequency of the wave is 50 Hertz (Hz).
