Problem 3CQ

For the graph in Figure Q14.9 , determine the frequency f and the oscillation amplitude A .

Solution 3CQ

Step 1 of 2:

We are going to find the frequency and the amplitude of the given waveform.

The wave started at 0 s with a certain non-zero displacement and ended at 4 s with the same value. There are two identical cycles in 4 s. Hence the oscillation has the time period (T) 2 s.

The frequency of oscillation

The frequency of the oscillation is 0.5 Hz.
