* 00 $寸 An electron microscope focuses electrons through magnetic lenses to observe objects at higher magnification than is possible with a light microscope. For any microscope, the smallest object that can be observed is one-half the waveleng th of the radiation used. Thus, for example, the smallest object that can be observed with light of 400.0 nm is 2.00 x 10 m. (a) What is the smallest object observable with an electron microscope using electrons moving at 2.60 x 10 m/s? SE X 10-8 (Enter your answer in scientific notation.)
