In each case you should demonstrate how you worked out your answer, as well as giving the answer. You mustms show your working to gain full marks. In each case, up to 50% of the marks are awarded for a clear explanation of your working.

A) sinewave has a frequency of 685 Hz (cycles per second). What is the corresponding period of this sinewave expressed in to 3 significant figures?

If the time period value you calculated above, is now reduced by a factor of 3, what will be the resulting frequency of the sinewave? Express your answer in kHz to 3 significant figures.

Note: In the second part of this question, to avoid possible rounding errors in your calculations, use the actual sinewave period value from the first part, not the rounded value to 3 significant figures.
