### Heisenberg's Indeterminacy Equation

Hi, I'm just still confused about how this equation can be used?

Thanks!

This equation is simply used to determine the amount of uncertainty which is present when calculating either the position or momentum of an electron.

The question could also ask the minimum uncertainty in velocity. For Heisenberg's uncertainty principle, be careful to notice what information is given. For cases where they give the radius size of an certain metal atom, make sure to double the length of the radius to get the diameter, which represents $\Delta$x. I suggest writing down what is given first and then write down the equation.

### Re: Heisenberg's Indeterminacy Equation

I am still a bit confused when inputting the given velocity into the equation. What I understand is if you are given something like 51 +/- 0.80, you would just use the .80 part for delta v. Somewhere in the book, there is an example like this, but they say to multiply by 2. So from this, would I just multiply .80*2? and then input that as my result? If so, why do we have to do this? I was thinking since $\Delta v=(v_2-v_1)/2$, but I'm still a bit confused on this part.

Multiplying by two will yield same result from doing the subtraction of max minus min of the speed range given.
