Question

A red laser is used in a double-slit experiment, producing the classic interference pattern on the back screen. If electrons were used, given a velocity such that their corresponding wavelength is the same as the wavelength of the red laser light, how would the corresponding spacing of the fringes compare to that of the red light?

The electron fringes would be farther apart than the red-light fringes.

The electron fringes would be closer together than the red-light fringes.

The spacing would be the same.
