A) photelecmcity and electron microscopy
B) light is refracted and diffracted
C) X-rays is diffracted, reflected by thick metal sheet
D) electrons have small mass, deflected by the metal sheet
Correct Answer: A
Solution :
Photoelectric effect can be explained on the basis of Plancks quantum theory. According to which light travels in the form of small bundles or packets of energy, hence stating the particle nature of light while electron microscope works on the principle of electron waves diffraction.
