Tools 100% A scanning electron microscope (SEM) is a microscope that uses a beam of electrons rather than visible light to produce images of specimens. Description of the Operation of an SEM Electrons are accelerated from the electron Electron gun gun to the anode. The electric potential difference between the electron gun and Electron beam the anode accelerates the electrons to a speed of 2.65 x 10' m/s. After this Andde acceleration, the electrons pass through an opening in the anode and enter the magnetic lens. Magnetic lens The magnetic lens focuses the beam of electrons. A particular electron experiences a magnetic force of 3.31 x 10 N while in the magnetic lens. As a result of this magnetic force. the path of the electrons spirals and the beam of electrons becomes locused. Scanning coils deflect the beam of Backseatteres electrons back and forth across the specimen. Some electrons from the beam reflect off the specimen at the same speed at which they hit. The backscattered electron detector picks up these elections. These hackscattered electrons provid. information about the composition and surface characteristics of the specimen. The electron beam causes the specimen in emit electrons from it's surface. The secondary elecuon detector pick - up these Tools Use the following additional information to answer numerical-response question 6 and question 18. In the SEM. some of the electrons in the original beam knock electrons loose from lower energy levels of the atoms in the specimen. An electron in a higher energy level of these atoms then makes a transition to fill the vacated lower energy level. The following energy level diagram shows two possible electron transitions in lead.

These waves are incident on a series of metal tubes that forms a diffraction grating. The metal tubes are spaced 1.80 cm apart When the microwave signal passes through the grating, a receiver placed 52.0 cm from the grating detects a maximum signal.
