Question: What is the frequency of a wave with a period of 0.2 seconds?

Options:

Correct Answer: 10 Hz

Solution:

Frequency (f) is the reciprocal of the period (T). Therefore, f = 1/T = 1/0.2 s = 5 Hz.

What is the frequency of a wave with a period of 0.2 seconds?

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.
