What did the Davisson-Germer experiment show? a.) Electrons can collide with objects, so they're always particles. b.) Electrons can produce interference patterns, so they're always particles. c.) Electrons can produce interference patterns, so that means they can behave as waves. d.) Electrons can collide with objects, so that means they can behave as waves. e.) Electrons can produce interference patterns, so that means they can behave as particles.
