An electron’s x-velocity uncertainty is found to be 4.12×104 m/s. What is its position uncertainty in nanometers in the x direction?
Use Heisenberg's uncertainty principle. Substituting the values
in relation we can find uncertainty in position.

Last questions of my semester!! Would be greatly appreciated. 1) A beam of light travels from a medium with an index of refraction of 1.29 to a medium with an index of refraction of 1.46. If the incoming beam makes an angle of 14.0° with the normal, at what angle from the normal will it refract? 2) Light passes through a pair of narrow slits with a 0.67-mm separation. It is found that the fourth bright fringe makes an...
A proton has velocity v=(1600± 0.15 )m/s . What is the uncertainty in its position? Express your answer using two significant figures.
What is the uncertainty of the position of an electron when the uncertainty in velocity is 1 Å/s? Group of answer choices a. 5.7 x 10-34 m b. 5.7 x 10-10 m c. 5.7 x 10+1 m d. 5.7 x 10+5 m
An electron has a momentum p≈ 1.7×10−25 kg⋅m/s. What is the minimum uncertainty in its position that will keep the relative uncertainty in its momentum (Δp/p) below 2.0%? Place final answer in 2 significant figures and convert answer to nanometers. The answer is NOT 15nm or 16nm from: x = h / [(4pi)(2%)(p)] = (6.626×10−34) / [(4pi)*(0.02)(1.7x10−25)]) = 15.5nm. Do not write this as the answer.
