Be sure to answer all parts. An electron microscope focuses electrons through magnetic lenses to observe objects at higheir magnification than is possible with a light microscope. For any microscope, the smallest object that can be observed is one-half the wavelength of the radiation used. Thus, for example, the smallest object that can be observed with light of 400.0 nm is 2.00 x 10m (a) What is the smallest object observable with an electron microscope using electrons moving at 3.70...

Be sure to answer all parts. The smallest resolution that a microscope can achieve is generally about half the wavelength of the particle probing the sample. For a visible light microscope, this means the smallest features that can be see are about 300 nm in size. The electrons in an electron microscope behave similar to light in a light microscope, having their own wavelength that can be calculated using the equation: λ = (6.626 × 10−34 J·s) / (m ×...
