Question

What period corresponds to 1 MHz?

Answer 1

`T=1/(1 MHz)=1/(1*10^3Hz)=1/(1*10^3 1/s)=1*10^-3s`

Explanation:

Hz is a frequency which is equivalent to `1/T` where T is the period. Since the prefix mega is `1*10^3`, the we can rewrite `1 MHz` as `1*10^3Hz`. Since Hz can be written as `1/s`the period is `1/(1*10^3 1/s)` leaving us with an answer of `1*10^-3s`
