I applied logic and got the answer wrong?
The question asked, what is time period?
I knew what frequency was. Freq=1/timeperiod which is 1000 , therefore my answer was timeperiod = 1x 1000 which is 1000 m/s.
The teacher's answer was time period 1/1000.
But, For example speed = distance/ time, to find distance= speed x time. shouldn't this concept apply to frequency as well.

Let f be the frequency and t the time period, just to save typing.
Then f = 1/t
Multiply both sides by t, and you get tf = 1
Then divide both sides by f to get t - the thing you want - on its own:
t = 1/f
This is the correct way to rearrange the formula.
speed = distance/time can rearrange to speed x time = distance, but if you wanted the time it would be time = distance/speed

Wrong. It should be:
Frequency=1000
Formula: Frequency=1/Time Period
So change the position:
1000=(1/Time Period)
Move the 1000:
Time Period=1/1000
Your teacher is right. (Correct)

What in the world are you carrying on about? You had the right answer at the start. Why do you work so hard to turn it into a wrong answer?
