What year was the Davisson-Germer experiment conducted?
1923
1930
1915
1945
Answer
1923 marked the groundbreaking Davisson-Germer experiment, which demonstrated the wave-particle duality of matter. By firing electrons at a nickel crystal, Clinton Davisson and Lester Germer observed a diffraction pattern, a phenomenon previously associated only with waves. This experiment provided compelling evidence that electrons, traditionally considered particles, also exhibit wave-like properties, solidifying the fundamental concept of wave-particle duality in quantum mechanics.
