Math Problem Statement
A sinewave has a period (duration of one cycle) of 535 μs. What is the corresponding frequency of this sinewave in kHz, expressed to three significant figures (see Study note 7.1 in the Using numbers (maths) booklet)? If the sinewave frequency is now increased by a factor of 4.25, what will be the new period value? Express your answer in ms to three significant figures. Note: in the second part of this question, to avoid rounding errors in your calculations, use the full frequency value from the first part, not the value rounded to three significant figures.
