The resolving power of a microscope depends on the wavelength used. If you wanted to "see" an atom, a wavelength of approximately 1.00 multiply.gif 10-11 m would be required.
(a) If electrons are used (in an electron microscope), what minimum kinetic energy is required for the electrons? (Hint: Use relativistic mechanics to solve this part.)
(b) If photons are used, what minimum photon energy is needed to obtain the required resolution?
Rocket-powered sleds are used to test the human response to acceleration. If a rocket-powered sled is accelerated to a speed of 444 m/s in 1.8 seconds, then what is the acceleration and what is the distance that the sled travels?
