A beam of electrons can
Correct answer: C. Both
- A. Reflect
- B. Refract
- C. Both
- D. None of these
Explanation
An electron beam can be refracted at the interface between a plasma and a gas, much as light is refracted at an air-water interface. Electron diffraction occurs as a result of elastic scattering when the incident electrons do not lose their kinetic energy in their interactions with atoms. In some cases, however, even inelastically scattered electrons can be diffracted as a result of an elastic interaction.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
