Final answer:

To find the speed of a proton with a de Broglie wavelength of 129 pm, use the de Broglie wavelength formula.


Explanation:

The speed of the proton can be calculated using the de Broglie wavelength formula:

λ = h / (m * v)

Given wavelength λ = 129 pm and mass m of a proton, solve for v to find the speed of the proton.

Remember to convert pm to meters before substituting the values into the formula.
