The diagram above shows a waveform in which energy is transferred from A to B in a time of 2.5 x 10-3s. Calculate the frequency of the wave
2.0 x 103Hz
1.0 x 103Hz
4.0 x 10-2Hz
1.0 x 10-3Hz
5.0 x 104Hz.
Correct answer is B
The waveform moved from A to B in 2.5×10−3 seconds.
From the diagram, A to B has 212 complete oscillations between it, Therefore, the period of the oscillation is
2.5×10−32.5=1×10−3s
Frequency=1Period
= 11×10−3=1×103Hz
