Diffraction is least when illumination is with
A)red light.
B)blue light.
C)an electron beam
D)none of the above

Question

Quizplus · Accepted Answer

Diffraction is directly related to the wavelength of the illuminating light or particle. Shorter wavelengths, such as those in blue light, result in more diffraction. However, an electron beam has a much shorter wavelength than visible light, resulting in very little diffraction. Therefore, option C is the best choice as it has the least diffraction.
