Question: 4. In an electron microscope electrons are accelerated by a 1500-V potential drop to a velocity of approximately 1x108 m/s. a) Calculate the de Broglie

4. In an electron microscope electrons are accelerated by a 1500-V potential drop to a velocity of approximately 1x108 m/s.

a) Calculate the de Broglie wavelength of these electrons.

b) What size objects should such a microscope be able to visualize? Explain your answer.

c) If you desire a minimum uncertainty in the position of the electrons in your microscope of 1 A, what is the maximum uncertainty that is acceptable in the momentum and velocity of the electrons?
