It's the celeb hair dye trend that's everyone's talking about, but is it worth the We earn a commission for Explanation: In scanning electron microscope (SEM), the surface of the specimen is irradiated with a very narrow beam of electrons. Such irradiations causes low energy (secondary) electrons to be ejected from the specimen which can then be collected on a positively-charged plate or anode thereby generating an electric signal. This brief assessment will test your understanding of a scanning electron microscope. The quiz consists of five short multiple-choice questions, including questions about how a scanning electron Multiple Choice Quiz on Electron Microscope.
