Uncertainty Value

[Doreen Liu 4D]

When the uncertainty is some value plus minus another value (e.g. 2.35±0.1 pm), is the uncertainty value 0.1 or is the value altogether the uncertainty?

[Ryan Chang 1C]

The uncertainty value would be 0.2pm because the position could be at 2.34 to 2.36.

[TarynD_1I]

the uncertainty value is 0.2 because the actual value would lie between 2.34 - 2.36.

The uncertainty value is 0.2 because you add .1 and subtract .1 from the given value, giving a total uncertainty value of 0.2.

The uncertainty value is 0.2 because you add .1 and subtract .1 from the given value, giving a total uncertainty value of 0.2.

What happens if the uncertainty is less than h/4pi?

[Michelle N - 2C]

Whenever there's a ±(number), the uncertainty would be taking into account both. :)

So in your case, ±0.1, it would be 0.2.

What happens if the uncertainty is less than h/4pi?

The best scenario would be equal to h/4pi.

The answer would be .2 because that's the value that is uncertain. It is the difference of the possible positions.
