What is the frequency of a wave, which has a period of 2 µsec?

• A. 0.5 MHz
• B. 2 MHz
• C. 1 MHz
• D. 0.2 MHz

Answer: (A)

To find the frequency of a wave given its period, you can use the formula: Frequency (f) = 1 / Period (T) Here, the period is given as 2 microseconds (2 µsec), which can be converted to seconds: 2 µsec = 2 × 10^(-6) seconds Now substituting this value into the formula: f = 1 / (2 × 10^(-6)) seconds Calculating this gives: f = 0.5 × 10^6 Hz or 0.5 MHz Therefore, the frequency of the wave is indeed 0.5 MHz, making this the correct answer. This means that the wave completes half a million cycles in one second, which aligns with the calculated frequency based on the given period. Understanding the relationship between period and frequency is crucial in power engineering, particularly when dealing with signal analysis and electrical systems.
