Final answer:

To calculate the de Broglie wavelength of a proton, use the equation = h / p, where is the wavelength, h is Planck's constant, and p is the momentum of the proton. Convert the distance traveled to meters, calculate the velocity, momentum, and finally, the de Broglie wavelength using the given formulas.

Step-by-step explanation:

To calculate the de Broglie wavelength of a proton, we can use the de Broglie equation:

λ = h / p

Where λ is the wavelength, h is Planck's constant, and p is the momentum of the proton. Momentum can be calculated using the formula:

p = m * v

where m is the mass of the proton and v is its velocity.

First, convert the distance traveled from kilometers to meters: 13 km = 13,000 m. Then calculate the velocity using the formula:

v = d / t

where d is the distance and t is the time. Plug in the values and calculate the velocity. Next, calculate the momentum using the formula:

p = m * v

Finally, calculate the de Broglie wavelength using the formula:

λ = h / p

Substitute the values for Planck's constant and momentum, and calculate the de Broglie wavelength.
