Smart Achievers · Accepted Answer

(1)

Davisson-Germer experiment showed that electron beams can undergo diffraction when passed through an atomic crystal. This established the wave nature of electrons, as waves can exhibit interference and diffraction.

Solution

1 Statement 1 is false, Statement 2 is true.

2 Statement 1 is true, Statement 2 is false.

3 Statement 1 is true, Statement 2 is true, Statement 2 is the correct explanation of Statement 1.

4 Statement 1 is true, Statement 2 is true, Statement 2 is not the correct explanation of Statement 1.
