Electrons go through a single slit 300 nm wide and strike a screen 24.0 cm away. At angles of =+_20.0° from the center of the dif- fraction pattern, no electrons hit the screen, but electrons hit at all points closer to the center. (a) How fast were these electrons moving when they went through the slit? (b) What will be the next pair of larger an- gles at which no electrons hit the screen?
