A sinewave has a frequency of 685 Hz (cycles per second). What is the corresponding period of this sinewave expressed in msto 3 significant figures (see Study Note 7.1 in the Using Numbers (maths) booklet)? 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.
