Question

An electron beam has properties of a: A. wave B. particle C. both

Answer 1

Solution-Both

Note-When electrons pass through a double slit and strike a screen behind the slits, an interference pattern of bright and dark bands is formed on the screen. This proves that electrons act like waves, at least while they are propagating (traveling) through the slits and to the screen. When an electron hits the screen, it produces a flash of light at just one place on the screen. The bright and dark bands are the result of the flashes of light produced by many electrons hitting the screen. Note that "hitting the screen" is an interaction, and the electron therefore acts like a particle with a definite position when it hits.
