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 wavelength of the radiation used. Thus, for example, the smallest object that can be observed with light of 400.0 nm is 2.00 × 107 m. (a) What is the smallest object observable with an electron microscope using electrons moving at 5.80 × 104 m/s? X 10 (select) m (Enter your answer in scientific notation.) (b) At 2.60 × 107 m/s? X 10 (select) m (Enter your answer in scientific notation.)

Question

Hello, i need assitance in solving the following question. 

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 wavelength of the radiation used. Thus, for example, the smallest object that can be observed with light of 400.0 nm is 2.00 × 10-7 m. (a) What is the smallest object observable with an electron microscope using electrons moving at 5.80 × 104 m/s? X 10 (select) m (Enter your answer in scientific notation.) (b) At 2.60 × 107 m/s? X 10 (select) m (Enter your answer in scientific notation.)
