world weight- lifting records agree well! ! 4. Please answer the following questions. (1) Use math to verify that, for a 300kV TEM system, the wave can be estimated without the consideration of effects of relativity (2) The real resolution of electron microscopes under 300kV explain why from two different aspects. (10 points) (3) For a 1000kV high voltage system, the wavelength of the correction (by using the theory of relativity) is 1.23 pm / 0.87pm, the wavelength of the e- beam with 1000kV acceleration voltage effects of relativity. (10 points) Note that
