Final answer:
The quantum wavelength associated with a high velocity electron is shorter compared to a lower velocity electron.
Step-by-step explanation:
The quantum wavelength associated with an electron with a high velocity is shorter than the wavelength of a lower velocity electron.
The de Broglie formula for wavelength is λ = h/(mv), where λ represents the wavelength, h is Planck's constant, m is the mass of the electron, and v is the velocity.
Since the formula includes the velocity in the denominator, a higher velocity will result in a smaller wavelength.
