(B)The spacing of the interference fringes increases as the speed of particlesincreases.
(C)The spacing of the interference fringes increases as the separation of slitsincreases.
(D)The spacing of the interference fringes decreases as the speed of particlesdecreases.
(E)The interference pattern is more significant for lighter particles with lowerspeed.
