Modern transmission electron microscopes have more than one electron source to increase the brightness of the electron beam. True False Question 5 1 pts The magnification of the final image is controlled by the condenser lens system. True False The Fourier transform of the Fourier transform of the Fourier transform of the object is the object. True False Question 7 1 pts The electron beam travels down the column of an electron microscope in a straight line. True False The extent of magnification of the electron microscope is dependent on the wavelength of electrons used to image specimens. True False Question 9 1 pts The electromagnetic lenses in the TEM are heated to >300K improve their electromagnetic strength and their ability to control electrons. True False During the preparation of an EM grid, the vitrification process should be long and slow to prevent ice nucleation and denaturation of particles at the air-water interface. True False
