In an electron microscope, electrons are used in place of light waves to create images of extremely tiny structures. The electrons are much easier to deal with than the light waves that have similar wavelengths (gamma rays). When the electrons are given the required kinetic energy, their wavelengths will be roughly 0.0037 nm. 24.96.91.88 Use the deBroglie equation to estimate the speed of these electrons. Enter your numerical result below as a multiple of 106 m/s. For example, if you wanted to enter the speed of light you would put the number 300 in the box, because C 3.00 X 108 m/s 300 × 106 m/s.
