| If a sine wave has a period T of 40 μs, its frequency is
A. 40 kHz
B. 250 kHz
C. 25 kHz
D. 2.5 kHz
Please scroll down to see the correct answer and solution guide.
Right Answer is: C
SOLUTION
Concept:
The frequency of a sin wave, given the time period, is given by:
\(f=\frac{1}{T}\)
This is explained with the help of the following diagram:
Calculation:
Given T = 40 μs
The frequency is therefore calculated as:
\(f = \frac{1}{{40 \times {{10}^{ - 6}}}}~Hz\)
f = 25 kHz
