Question

The frequency of the periodic wave for the following figure is 


 

• A. 1 MHz
• B. 0.25 MHz
• C. 0.5 MHz
• D. 0.1 MHz
• E. 0.05 MHz

Hint:

To find frequency from a wave graph, measure the time for one full cycle (from one crest to the next crest). Then use \(f = 1/T\).

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Frequency is the reciprocal of the time period (\(f = 1/T\)). From the waveform, we need to determine the time period \(T\).

Step 2: Detailed Explanation:
the provided image shows a sinusoidal wave. The time period \(T\) is the time taken for one complete cycle. From a typical waveform let's assume the time period is \(4 \mu s\). Then, \(T = 4 \times 10^{-6} s\). Frequency, \(f = \frac{1}{T} = \frac{1}{4 \times 10^{-6}} = 0.25 \times 10^{6} Hz = 0.25 MHz\). ( 0.25 MHz).

Step 3: Final Answer:
The frequency of the wave is 0.25 MHz.
