Question

What is the equation for the uncertainty principle?

Answer 1

The exact formula for calculating the uncertainty of an electron is:

Δx > h/4πmΔv

Where:

Δx = the uncertainty
h = 6.626 x 10-34 J-s
m = mass of electron (9.109 x 10 -31 kg)
Δv = the degree of certainty you are given (e.g. "speed is known to within 0.01m/s")
