- Find the wavelength.For a given accelerating voltage, an electron microscope has a certain theoretical resolution. Suppose that instead of a beam of electrons you used a beam of protons, with the same accelerating voltage. How would this affect the theoretical resolution?After you calibrate the SpectroVis Plus spectrometer, you must a. run a full spectrum by selecting Sensors/Calibrate/Full Spectrum. O b. change the mode by selecting Sensors/Time-Based. Oc. collect a full spectrum of the sample to determine the wavelength of maximum absorbance. O d. change the mode by selecting Sensors/Data Collection.
