a propos the uncertainty in what ?

faiqraees · Answer

I didnt understood your question @IrishBoy123

faiqraees · Answer

So uncertainty is basically the change in frequency that can occur because of the inaccruacy of the scale.
We can calculate the actual frequency which is 526Hz but what is the uncertainty in this frequency because the scale is accurate to 0.2cm

Btw got it 
Absolute uncertainty = 50% of lowest count = 0.5*0.2=0.1
since we look at the scale two times = 2*0.1 = 0.2
Percentage uncertainty of time = 0.2/3.8 *100 = 5.26%
Percentage uncertainty of frequency = percentage uncertainty of time
Percentage uncertainty of frequency = 5.26%
Abosulte uncertainty/Absoulte value = 5.26%
Absoulte uncertainty = 27
