G P Thomson experimentally confirmed the existence of matter waves by the phenomena

Correct answer
A
diffraction
B
refraction
C
polarisation
D
scattering

Solution

G P Thomson experimentally confirmed the existence of matter waves (de-Broglie's hypothesis) by demonstrating that electron beams are diffracted when they are scattered by the regular atomic arrays of crystals.

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