Consult your textbook pages 146-147. Determine the frequency of the waves depicted on those
pages. Note that the scale is in milliseconds (1 sec. = 1000 ms). If relevant, round your answers
to the nearest whole number.
Frequency of sine Wave A in Figure 7.16:
125Hz
Frequency of sine Wave B in Figure 7.16:
167Hz
Frequency of complex wave in Figure 7.17:
143Hz
If a wave has a frequency of 625 Hz, then each cycle lasts
0.0016
seconds.
