Q159 / 180 · COMEDK 2012 · Physics

Choose the wrong statement.

A
Alpha particles can be scattered by Gold nucleus.
B
X-ray can be diffracted by crystals.
C
UV-radiation can cause photoelectric effect.
Correct answer
D
Electrons cannot be diffracted by crystals.

Solution

Electron wave is used in place of X-rays to study crystals of larger dimensions in electron crystallography. So, they can be diffracted.

Hence, the correct answer is option: 'D'.
