# For λ = 5.0 X 10^5m calculate the (i) fractional uncertainty in d. (ii) percentage uncertainty in d^2 ?

##### 1 Answer

See below:

#### Explanation:

For (i):

From my measurement by eye, it seems that the point where

So the fractional uncertainity is:

Uncertainties:

When two values are multiplied with uncertainties use the formula (Section 1.2 in the Physics Data booklet):

as

If

Then the uncertainties are:

hence:
