Davisson-Germer, Uncertainty, Compton & X-Rays
This question has Statement 1 and Statement 2. Of the four choices given after the statements, choose the one that best describes the two statements.
Statement 1: Davisson - Germer experiment established the wave nature of electrons. Statement 2: If electrons have wave nature, they can interfere and show diffraction.
Show answer and solution
Answer: (b)
- Statement 1: Davisson and Germer observed electron diffraction from a nickel crystal, which proved the wave nature of electrons. True.
- Statement 2: Interference and diffraction are wave properties, so waves of electrons must show them. True.
- Their experiment worked exactly because electron waves diffract, so Statement 2 explains Statement 1.
- So the answer is (b).
