Which of the Following Techniques are Based Upon Wave Interference

Question

Which of the following techniques are based upon wave interference?
A) X-ray diffraction and phase contrast microscopy
B) phase contrast and dark-field microscopy
C) bright-field and dark-field microscopy
D) X-ray diffraction and atomic force microscopy
E) scanning and transmission electron microscopy

Accepted Answer

X-ray diffraction relies on the interference of the waves of X-rays passing through a crystal lattice, while phase contrast microscopy is based on the interference of the waves of light passing through different parts of a transparent specimen.
