Electrons go through a single slit 300 nm wide and strikea screen 30.0 cm away. At angles of +-20.0° from the center of the diffractionpattern, no electrons hit the screen, but electrons hit at all pointscloser to the center. (a) How fast were these electrons moving whenthey went through the slit? (b) What will be the next pair of larger anglesat which no electrons hit the screen?
In A Compton Experiment, the ultraviolet ray of wavelength 2000A° is scattered from an electron at rest.If the observation of the scattered X- rays is made at 90° with respect to the Direction of incident light, then to measure the Compton shift, resolving power of an optical instrument that will be needed is ?
