Answer:
violet
Explanation:
When an electron interacts with visible light, energy is transferred from the photon to the electron.
The most accurate (lowest error) measurement of momentum (or speed) of an electron is obtained using a photon of high energy and low wavelength.
Violet light which lies at the high energy end of spectrum is most suitable.
Magnetic is a physical property.
